Update `ownerapi_endpoints.json` to `v4.21.0-1717` & Update Docs 🔗📚

[core-hacked]

Changes:

• Update ownerapi_endpoints.json on par with App v4.21.0-1717.
• Document the new way of requesting what the data_request endpoints returned.
• Remove obsolete endpoint from docs/summary
• Update summary to feature new endpoints/states
• Update some responses on par with the above changes.

Notes: Two unknown states have been added/used by the app. closures_state and location_state. Location State might change if the car is in motion, someone needs to check that, I haven't had the time to check yet. Maybe Car/Config related. What closures state is, I have no idea.

Owner API endpoint notes: Just BFF endpoints. No breaking changes or new endpoints on ownerapi url.

I cherry-picked the endpoints updates for now. I'm going to mull over these larger changes for a sec. I just want to be sure we've got things organized in the right way, so it's not overwhelming or confusing for new users.

When I get the time I will move the doc changes to a separate PR so there are no unrelated/already merged commits. For now this can stay open. I will make a new PR once the above is done.

Kind Regards!
