github portgroup regex stopped matching

[Blair Zajac]

Maybe something has changed on github.com just now, however, a number of ports using github now don’t match:

$ port livecheck protobuf3-cpp yarn timescaledb
Error: cannot check if protobuf3-cpp was updated (regex didn't match)
Error: cannot check if yarn was updated (regex didn't match)
Error: cannot check if timescaledb was updated (regex didn't match)
