Feature request: support regular git repos

[capaj]

I recently made this tool: https://github.com/capaj/contrib-locs

and seeing that you only support github/gitlab with this CLI, it should be possible to add support for a general git repo. Not sure about user avatar images though.

That's a good point, I don't know if there has been a demand for it for services like Bitbucket but if there is then a PR would be welcome!
