Motivated by ofborg struggling [1] and its evaluations taking too long, inspired by Jörg's initial PR [2] and Adam's previous attempt to parallelise Nixpkgs evaluation [3], this PR contains initial work to relief ofborg from its evaluation duty by using GitHub Actions to evaluate Nixpkgs. For now this doesn't take care of all of what ofborg does, such as requesting appropriate reviewers or labeling mass rebuilds, but this can be follow-up work.
