GitHub Actions: V2 cache actions

We have released v2 versions of the cache actions.

New features:

• Added support for caching multiple paths, wildcard patterns path or single file path
• Increased performance and improved cache sizes using zstd for compression for Linux and macOS runners
• Allowed caching for all events with a ref
• Created the @actions/cache npm package to allow other actions to utilize caching
• Added a best-effort step to delete the archive after extraction to reduces storage space
