Support GitLab projects

[MattIPv4]

👋 Hacktoberfest allows for folks to contribute both to projects on GitHub as well as on GitLab. Looking at the code here, it appears to only fetch opted-in projects on GitHub. It'd be great to see support for GitLab added as well! Cheers.

Yea this is needed. I'll see what I can do with GitLab API and let me know if you would like to take this up ✌️
