Entra ID replacements and clearer wording of token

[erwinkramer]

1. Use EntraId throughout the documentation instead of AzureAd.
2. Microsoft Entra Identity isn't a product name as far as i know, it's Microsoft Entra ID, replaced all occurrences.
3. Clearer "X-MS-API-ROLE request header" paragraph. I used the wording "access token's roles claim" and "access token" instead of just "token", because those are used in other parts of the documentation as well.
