Add hybrid ML-KEM to the list of TLS Curves

[nuxi]

X25519MLKEM768 is a hybrid post-quantum key agreement scheme. I believe this should be added to the list of TLS curves in order to mitigate a store now, decrypt later attack.

Firefox has supported this algorithm since version 132 on desktop (bug 1919097) and will support it on Android starting with version 145 (1989986)

Chrome also supports this algorithm. I believe since version 124 although I'm not 100% sure.

edit: fixed some terminology. ML-KEM was previously known as Kyber. Also this is a hybrid PQC algorithm.
