This PR ensures that only the last execution per branch always works, even when pushed multiple times in a row, for example. The older one is canceled.
I find myself pushing often, and with many jobs the GHA limit them to a certain amount of concurrently running jobs.
This limit is applied per-org, so if there's a running rspec-rails build means the rspec-core build jobs will spin in a queued state until the first build jobs start to release job slots.
