Documentation Feedback

We should first test the compatibility of react-native-app-auth with the new Entra ID (it should work charm as it works with Azure AD since it's mostly the same behind the scenes) in the list of providers page and some documentation.

Entra ID: https://www.microsoft.com/en-us/security/business/identity-access/microsoft-entra-id

@ududsha @carbonrobot I tested the demo app with the config example used in my PR here #1044, and it works perfectly. Take a look and let me know if we can make the documentation more detailed/useful
