Add a rebase on top of BASE_REF before the pytest run to make sure that
PRs that predates the test introduction runs on top of the current HEAD.
This prevents pytest from failing with error code 5 because no tests are
found.

Add a "Scripts tests" workflow, for now just run pytest against
"scripts/build", but keep the naming generic so this could be reused for
other tests under scripts that are not covered by the other workflows.
