Update Authorization Code client_secret kwarg usage (#34862)

* fix client_secret
- use from get_token method if present
- use from init if not in get_token

* consume client_secret kwarg

* fix lint errors.

* test client secret.

* remove client_secret from get_token
- client_secret should be utilized from within the constructor instead of the method call

* add client_secret to get_token method.

* lint
