Description
One area for improvement is that currently the action caches the mathlib cache generated by lake exe cache get which seems redundant and takes up significant space in the GitHub cache.
One potential fix for this would be to exclude certain subfolders of .lake from the cache. This behavior of the cache action may be relevant.
