Run all tests if package-lock.json changes

If one of our dependencies changes it can have an effect on all tests we
have, for instance via the test runner, bundler or coverage collector.
This commit therefore updates all workflows that work with a file-based
allowlist to also trigger on `package-lock.json` changes so that we have
more certainty that any unintended effects of dependency updates can't
go by unnoticed, and thus improve stability.
