chore: Update quic-go to v0.42.0 (#6176)
* update quic-go to v0.42.0 * use a rate limiter to control QUIC source address verification * Lint * remove deprecated ListenQUIC * remove number of requests tracking * increase the number of handshakes before source address verification is needed * remove references to request counters * remove deprecated listen* --------- Co-authored-by: Francis Lavoie <lavofr@gmail.com> Co-authored-by: WeidiDeng <weidi_deng@icloud.com>
