-    # We do not use npm ci (short for clean install) because it removes the existing node_modules folder. But we want to

-    # same purpose, we reset the package lock file after running npm install. Sometimes npm install updates the lock
-    # file and that will also break caching because its checksum would then change between save_cache and restore_cache
-    # in the next CI run.
