Doesn't support save/restore as separate actions

[palfrey]

actions/cache (even the v3 versions) has restore and save as separate actions, but not this repo. There's the dist folder with the separate files, but doing something like uses: pat-s/always-upload-cache/[email protected] gets Error: Can't find 'action.yml', 'action.yaml' or 'Dockerfile' for action 'pat-s/always-upload-cache/[email protected]'.
