Subject: [PATCH] Skip cache delete job for forked PRs

Dependabot and forked PRs don't have 'write' permission to delete the
GitHub Actions caches.

Skip this step for those kinds of PRs. It will keep the caches around
for longer than we'd like, but at least it won't balloon in size if we
skip this for all PRs.
