Make sure that this works when ssh key is not available

The git@github.com:nebari-dev/nebari.git format works well when ssh key is setup but not when using an anonymous git user - in that case https://github.com/nebari-dev/nebari.git is needed.

We will need to improve URL parsing so that we can switch a valid git URL given in one format to another format but using the protocol that we need. It is easy but probably time consuming and requires writing tests.
