HTTP/3: fixed server_name regex captures (ticket #2407). Previously, HTTP/3 stream connection didn't inherit the servername regex from the main QUIC connection saved when processing SNI and using regular expressions in server names. As a result, it didn't execute to set regex captures when choosing the virtual server while parsing HTTP/3 headers.
