PUT /me/tokens: Return crate_scopes and endpoint_scopes fields too

[Turbo87]

#5973 already changed this endpoint to accept these fields in the request payload, but the endpoint did not return them again in the response. #6310 changed the corresponding GET endpoint to return these fields in the response, and now this PR here is adding them to the PUT response too.

Note that these fields are considered experimental and we don't give any stability guarantees for now!
