mod_http_oauth2: Advertise the currently supported id_token signing algorithm
This field is REQUIRED. The algorithm RS256 MUST be included, but isn't
because we don't implement it, as that would require implementing a pile
of additional cryptography and JWT stuff. Instead the id_token is
signed using the client secret, which allows verification by the client,
since it's a shared secret per OpenID Connect Core 1.0 § 10.1 under
Symmetric Signatures.
OpenID Connect Discovery 1.0 has a lot of REQUIRED and MUST clauses that
are not supported here, but that's okay because this is served from the
RFC 8414 OAuth 2.0 Authorization Server Metadata .well-known endpoint!
