(DOCSP-39526): Consolidate Authenticate Users page

[dacharyc]

Pull Request Info - SDK Docs Consolidation

Jira ticket: https://jira.mongodb.org/browse/DOCSP-39526

Staged Page

• Authenticate Users
• Manage User Tokens: New page that moves the user access token info off the "Authenticate" page. This is currently a separate page in Flutter. As devs shouldn't have to handle this manually for most use cases, and the OTP is getting super long, I thought it made sense to move the info off to a separate page.

Page Source

Add links to every SDK's pages where you got the SDK-specific information:

• C++: Authenticate Users
• Flutter: Authenticate Users
• Flutter: Get an Access Token
• Java: Authenticate Users
• Kotlin: Autenticate Users
• .NET: Authenticate Users
• Node.js: Authenticate Users
• Swift: Authenticate Users
