fix: Git ssh-scp syntax (#69)

Browse source 
* fix(deps): proper git ssh scheme

* feat(deps): git scp style

Adds support for the git ssh-scp style (`git@github.com:user/repo.git`),
which is an alternative form for ssh (note no ssh://).

* fix(deps): githubSlug also matching gitSSH

* test(deps): other hosts than github
