refactor(tests,tooling): unignore `ARG001` in `tests/*`

The unused arguments in the tests directory may have important side effects or indicate a bug in the test code. Removing them requires more careful investigation.

> @SamWilsn, could you please revert the changes and apply `# noqa: arg001` to all of the instances found under `./tests/`. Let's make an issue to follow up and do that work in a subsequent PR. Then I think we can get this merged.
