Updated to checkout the code first since not all workflows(merge_queue)
will check have the PR_URL setting set. Then grab the shas from the
relevant event payload and use those to get the list of affected files.
This reverts commit 52adce48d1 because we were getting this in the build pipeline:
```

This skips the `make compile-requirements` check when there have been
no changes under `requirements/**`, but it does so in a way that still
registers the action as having passed, not skipped. By doing so, we
can make it a required check while also avoiding the 5-6 minutes of
wasted worker time.
This commit also removes the activation on push-to-master, since we really
just need to check PRs. I don't expect there to be silent merge conflicts
with this check, so if it passes on a branch it should also pass on a
successful simple rebase or merge.
It would be nice if there was a way to declare success and exit early,
but GH hasn't implemented it: https://github.com/actions/runner/issues/662
Alternatively, it would be great if skipped checks could count as
fulfilling the branch protection rules, but no luck there.
The only alternative that uses GH's built-in paths/paths-ignore
feature would be to add a second workflow with the same job name and
the opposite path triggers and that always passes. It's not clear that
this would be any less fragile or confusing than the `git diff | grep`
and step-conditionals approach.
We have a few situations where requirements files can become
inconsistent or cause unnecessary review churn in later `make upgrade`
runs either due to manual editing, inconsistent environments, or
incorrectly specified git dependencies. This will produce a failing
check for any PR that does not produce a clean run of `make
compile-requirements` on Linux.
