(DOCSP-39526): Consolidate Authenticate Users page (#3281)

## Pull Request Info - SDK Docs Consolidation

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

*Staged Page*

- [Authenticate
Users](https://preview-mongodbdacharyc.gatsbyjs.io/realm/DOCSP-39526/sdk/users/authenticate-users/)
- [Manage User
Tokens](https://preview-mongodbdacharyc.gatsbyjs.io/realm/DOCSP-39526/sdk/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](https://www.mongodb.com/docs/atlas/device-sdks/sdk/flutter/users/access-token/).
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:

Users](https://www.mongodb.com/docs/atlas/device-sdks/sdk/cpp/users/authenticate-users/)
