Fix JwtClaimValidator wrong error code

Previously JwtClaimValidator returned the invalid_request error on claim validation failure.
But validators have to return invalid_token errors on failure according to:
https://datatracker.ietf.org/doc/html/rfc6750#section-3.1.
Also see gh-10337

Closes gh-10337
