Minor Clarification Update to Profile Service Docs (#5101)

* Update profileservice.rst

Misleading, as going by the [code](https://github.com/IdentityServer/IdentityServer4/blob/7cf6192d0aceb48f8c938e828bf8c4f4c1b0fba3/src/IdentityServer4/src/Services/Default/DefaultClaimsService.cs#L113), access tokens doesn't actually get their claims via Identity Resources.

* Update profileservice.rst
