Low confidence approval. How do we know this worked?

@carmocca Thank you for your review!

Low confidence approval. How do we know this worked?

We can try running this workflow on this PR once, but that will increase the testing time across (almost) all PRs in this repository. I can test it out this weekend and will paste the link to the job run to make sure that it resets these caches.
