update quic-go to v0.59.0

[marten-seemann]

Update dependency github.com/quic-go/quic-go to v0.59.0 and adjust test helper assertions in test_helper_test.go to use SupportsDatagrams.Remote

Bumps github.com/quic-go/quic-go to v0.59.0 in go.mod with corresponding checksum updates in go.sum, and changes newConnPair assertions in test_helper_test.go to check SupportsDatagrams.Remote for both client and server.

📍Where to Start

Start with the newConnPair test helper in test_helper_test.go to review the assertion changes, then verify the dependency bump in go.mod.
