CleanUpDiskOccupancy

Clean up the vscode cache, which will reach 30g.

rm -r "/Users/<user>/Library/Application Support/Code/Service Worker/CacheStorage"

two。 Clean up the Docker cache, which will reach 50 GB. Docker settings: docker image size turn it down

3. Clean the yarn and npm caches, which will reach 20 GB.

This set can release about 70G of space
