`sl pr submit` does not support organization-specific GitHub URLs.

[tpcstld]

GitHub suggests organizations that use SSH certificates to set their remotes to an organization specific URL. https://docs.github.com/en/enterprise-server@3.11/organizations/managing-git-access-to-your-organizations-repositories/about-ssh-certificate-authorities#about-ssh-urls-with-ssh-certificates

The format of this URL is ssh://org-1234567@github.com/foo/bar.git.

Running sl pr submit with the default path set to such an URL fails with abort: could not parse GitHub URI: <url>
