Per testing task RHELMISC-11986 post-quantum cryptography in TLS, I discovered that yggdrasil-0.4.6-1.el10.x86_64 failed to connect to a server capable of post-quantum crytography.  Instead of connecting with a desirable X25519MLKEM768 key exhange, x25519:secp256r1:secp384r1:secp521r was the best it could do with an RSA certificate and failed to even parse a ML-DSA certificate key.

Solution: Rebuild yggdrasil with go version 1.24, as suggested in https://pkg.go.dev/crypto/tls#pkg-overview...

	// From Go 1.24, the default includes the [X25519MLKEM768] hybrid
	// post-quantum key exchange.

The steps to reproduce the testing failure are in this RHELMISC-11986 comment.
