Update Docs for Microsoft Entra ID login

### Current Behavior

Entra ID login fails with configuration according to the docs

### Proposed Behavior

Docs describe a working method for Entra ID.

I am open to adjust the docs according to [this SO post](https://stackoverflow.com/questions/79688483/unable-to-login-to-dependency-track-using-microsoft-entra-id-azure-ad-account) because the groups claim returns `null` and the configuration currently described in the docs does not work. The underlying issue seems to be #2150, but for as long as that is not fixed, I guess it makes sense to adjust the docs to something that actually works.
