Add support for cloning git repositories using SSH

Is your feature request related to a problem? Please describe.

After closing #147, you can use a remote git repository as a valid location. However, it only clone repos over HTTP/S. The following command doesn't work:

wws git@github.com:vmware-labs/wasm-workers-server.git

Describe the solution you'd like

I want to clone git repositories using the SSH protocol too. It will require to detect these kind of URIs, load the SSH key and try to pull it. For the SSH key, I need to evaluate the different options. From the git2-rs library, you can load it from a file, the memory or a ssh-agent.

You may need to add more git options to the CLI so you can get SSH keys location, agent usernames, etc.

Yes! That's the main reason why we created a separate task for this. We would need to add more configuration options for managing auth methods. I will try to complete the implementation details on the issue to discuss about them 👍
