feat(ci): Clean up the actions cache on PR close (#1350)

* feat(ci): Clean up the actions cache on PR close

The cache entries that are generated on a workflow run for a PR cannot be used by any other contexts [1]. As such, they are useless and just wasting valuable cache space. This commit adds a workflow (copied from [2]) that deletes the cache entries when a PR is closed.

* feat(ci): List as many cache entries as possible
