Run our CI only on pushes to the main branch, not to any branch. This makes sure CI doesn't start on branches of forks, which is a waste, since we run CI on our pull requests anyway. Branches on forks are meant to be merged into the main repo through a PR, so running CI on the branch is not necessary.
