Clean Up Cache Entries

[h3h]

Similar to #31 perhaps, but I noticed that MNC really cluttered up my GitHub Actions Caches.

When opening the Caches view in GitHub (organizations/<org>/settings/actions/caches), there were ~100 entries of long alphanumeric strings, none of which are useful or intelligible from a cache management standpoint, and which are also tedious to delete if one wants to force purge the caches.

Could all caches be combined into a single entry in GitHub’s Caches, with a customizable name?
