PyJWKClient.get_signing_key_from_jwt method is not correctly type annotated. Even though the underlying code expects str | bytes, the jwt argument is only annotated with str.

Expected Result

A def get_signing_key_from_jwt(self, token: str | bytes) -> PyJWK: annotation, allowing the library users without having to extraneously decode the jwt.

Ideally, a single JWT: TypeAlias = str | bytes type exported for the library users and used in all relevant annotations.
