When token introspection was introduced in 6f5d19a, using the code that previously only handled token revocation, the new `_handle_token_hint` method that does the work for both `introspect_token` and `revoke_token` kept using `self.revocation_endpoint_auth_method` unconditionally if no `auth` was passed in with the introspect or revoke request. This seems to be wrong, introspecting a token should use the `token_endpoint_auth_method`. This leaves the fallback to `revocation_endpoint_auth_method` in `_handle_token_hint` because adjusting its signature to make `auth` compulsory would be awkward, but it's not expected ever to be used.

As I work for Red Hat I cannot agree to "consent that the copyright of your pull request source code belongs to Authlib's author" without my employer's permission, but I think this change is too trivial to be copyrightable. |

I have discussed with @lepture, and he is OK about the copyright thing. |
