GHE.com support broken for SSH/Git remote URLs

[gustavkj]

Describe the bug

It appears that the implementation of https://github.com/github/vscode-github-actions/issues/457 through https://github.com/github/vscode-github-actions/pull/458 was broken by https://github.com/github/vscode-github-actions/pull/469 if you are not using http remote urls and instead use the SSH/Git remote urls, e.g. <company>@<company>.ghe.com:org/repo.git.

Log output:

Activating GitHub Actions extension...
Error getting GitHub context

To Reproduce Steps to reproduce the behavior:

1. Set up a repo on a ghe.com instance. Add VS Code settings as follow:

   {
      "github-enterprise.uri": "https://<company>.ghe.com",
      "github-actions.use-enterprise": true
    }
   

2. Check out the repository using the git/ssh remote:

   git clone <company>@<company>.ghe.com:org/repo.git
   

3. The Github Actions extension will fail to initialize due to URL failing to parse <company>@<company>.ghe.com:org/repo.git as a URL which then throws an error which is not handled.
