Fix RFC 8414 path-aware authorization server metadata discovery (#2533)
* Fix RFC 8414 path-aware authorization server metadata discovery

Override get_well_known_routes() in OAuthProvider to rewrite the
authorization server metadata route to be path-aware based on issuer_url,
matching how protected resource metadata already works.

Closes #2527

* Update readme
