fix(github): recognise remotes cloned through ssh.github.com

A repository cloned over GitHub's SSH-over-HTTPS host (ssh://[email protected]:443/o/r.git) wasn't recognised as a GitHub repository, so pull requests and issues weren't offered for it. The host is accepted for SSH remotes; https://ssh.github.com is still not a GitHub web URL.
