Description
RFC 9964 adds the post-quantum ML-DSA signing algorithms to JWS. The algorithm is already supported by OpenSSL, LibreSSL, and GNU TLS and we should support it in libcups 3.1.

Research direction
Start by reading RFC 9964 and locating libcups' existing JWS signing implementation. Compare its supported algorithms with ML-DSA support in OpenSSL, LibreSSL, and GNU TLS. Done means libcups 3.1 can use the ML-DSA JWS signing algorithms.
