Document userinfo endpoint

Description

What did you add/update/change?
Documentation of new userinfo endpoint from Umbraco 13.6+
umbraco/Umbraco-CMS#17719

Also document of this part would be great, e.g. a custom properties from member like firstName and lastName:

The implementation is build to be extendable, so custom claims can be added to these claims - and the core claims can be removed, too.

Perhaps it should be mentioned sub contains Umbraco member guid key, but not sure if it always guid if integration with external providers.

@kjac it seems sub is member key/guid in this this, but I guess it could be something else with external provider or if overwriting key.

It would also be great somewhere to place to .NET part:
