+description: >-
+  Remove the caches that were generated to a PR once that PR is closed. These
+  caches cannot be used by the default branch or by other branches and
+  therefore have no use anymore. See also
+  https://github.com/actions/cache/blob/main/tips-and-workarounds.md#force-deletion-of-caches-overriding-default-cache-eviction-policy.
