Remaining TODOs for this PR

[x] Check that the connectionUri returned from saas apps get API only has the actual domain part in it when being used in <CoreInjector> component, since we add appid-<APP_ID> in the url of the curl snippets
[x] Check that not using _default thing anywhere in the docs since we have the getRequestFromContext function now
[x] In mobile login with apple, we are saying that we need to send id token to the backend, but the curl command sends auth code instead. We need to update the doc to make it correct
[x] Change title of guides to replace social login with social / enterprise login and even in drop down menu
[x] On the intro page, in the heading, remove the "login with supertokens" postfix.
[x] Multiple sub domains should talk about what to do for appInfo and for email links
[x] cURL command for creating a new tenant has multi tenant / single tenant code tabs. Make that multi app / single app instead. Other curl commands in docs like importing users should continue to have multi tenant / app code tab.
[x] In "Step 6: Limiting the user's access to their sub domain" of sub domain based login, focus on frontend first, and then for backend, clearly mention that it's a niche use case where you have a different api domain per tenant.
[x] What do we do about "additional features" section since it only contains user roles now.
[ ] Need to confirm that the react code for submitting the tenantId in “common-domain-login” is correct.
[x] Check that the proper connection uri is set in the core injector component
[x] Change the cURL commands to not use tenantid in query param, but instead use it in path (for mobile tabs).
[x] In common sub domain case, don't use localstorage, and instead, use sessionStorage to store the tenantId in the example.
[x] In common ux flow for sub domain based login, having mobile tab makes no sense.
[x] In the multi tenancy getAllowedDomains, we only return the frontend sub domains and not API domains
[x] Make sure that all web-js-script import for multitenancy use supertokensMultitenancy and not just multitenancy.
[x] Update docs for password reset, email verification and magic link to have query param of tenant id.
[x] Double check the changes made for node sdk to make sure that it's in tandem with golang.
[x] Change docs for updating email / phone number of a user to account for the fact that that email may exist in one of the tenants that that user already belongs to
[x] Check in code types that in web-js, getAuthorisationURLWithQueryParamsAndSetState does not take an optional tenantId
[x] Temporarily make all index functions take tenantId compulsory so that we can see in docs where all the tenantId needs to be passed through in the example code snippets.
[x] Frontend SDK should not expose providers like it used to - it should be similar to the backend.
[x] Wherever we use allowedclaims on the frontend for auth-react, make sure to incorporate validator callback related docs in it.
[x] Session sharing across sub domain for different tenants will still give tId in session as the one that was used for login. So the dev has to add extra logic to get the right tId - mention this in docs for common UX flows for multi tenancy.
[ ] Check that cURL commands for creating a saas app is correct (for example, they should use PUT and not POST).
[x] Change the docs for other customisations (like invite flows) to also account for tenantId.
[x] For mobile code snippets or for custom UI, mention that for reset password links (and other links), tenantId is in the link as a query param.
[x] Check that we are storing tenantId in localstorage in common UX flows, and not in sessionStorage
[x] how to fetch the tId from the JWT in manual verification process.
[x] Write how to get tenant id on the backend from a session
[ ] Update the guide and example app for updating user's email by using the new functions from our SDK
[x] For content specific to multi tenancy, we create a custom react component in purple and only show that if the code tab for multi tenancy has been selected. The paid feature banner should also be in the same purple
[x] Colour scheme for custom admonitions
[x] Update session claim interface to include tenant ID.
[x] Where are the docs for changing passwordless user's phone with verification?
[x] New app creation should have all login methods enabled by default.
[x] Add a new section about editing app config in docs (for core in multi tenancy recipe docs)
[x] Update example app for changing email to not check for if email exists before hand.
[x] revokeAllSessionsForUser and getAllSessionHandlesForUser should talk about behaviour when tenantId is not passed in (they work across all tenants).
[x] "Coming Soon" in flutter docs in social login under "Flow 2: Via OAuth / Access token (Sign in with Google example)" needs to be rendered correctly.
[x] Update email docs should check if the email is already associated with another user before doing email verification.
[ ] For python and golang, in post login email change docs, in method 2, we need to check if the email exists for any tenant that the user is a part of.
[x] Add docs for how to disable interception for our SDK for your backend APIs
[x] Change title of action hooks part to also include frontend UI customisation
[x] Go through docs for user roles and make sure that it's per app in role creation / permission creation. But per tenant in user to role mapping. Also add info about multi tenancy use.
[x] Go through user metadata docs to make sure it's per app
[x] Add docs for user sharing across tenants
[x] getUserCount needs to say that by default it's across all tenants for the app.
[x] user pagination needs to say that it's per tenant only
[x] for page that talks about sharing users across tenants, add code snippet for backend sdks as well.
[x] Disable mocking of APIs.
[ ] Check coreinjector putting in right uri with older and newer APIs in prod.
[x] Add note about multi tenancy where we call updateEmailOrPassword to say that you can pass in a tenant id for password validation
[x] Add a not about form field validators saying that you can have different logic for different tenants
[x] MFA docs changes
[x] Check if claim.build(..) is being called anywhere, and if it is, pass in tenantId as well
[x] Add section on rate limits
[x] Add docs to get tenant id in multi tenant section on the backend
[x] How to get a list of all tenants in the app
[x] Add in hasura docs and aws docs where we say to use JWT that the claims need to be checked by you.
[ ] In websocket session management, we need to mention that the claims should be checked properly.
[ ] For frontend npm i, say to use the older version in the docs.
