[anti-censorship-team] What to do with the now-unused go-webrtc repository?

Since #28942, Snowflake no longer uses the go-webrtc library. (Actually server-webrtc still uses it, but server-webrtc itself is hardly used.) I opened a ticket (at GitHub, where go-webrtc is hosted) to discuss what to do with it, especially by third parties who may not know that its maintainers aren't working on it actively any more. https://github.com/keroserene/go-webrtc/issues/109
