fix: wireit sass watch memory leak

[vdegenne]

This will avoid wireit looping through the @material/web symbolic link in watch mode.

@e111077 wait!

if there's a change you need to be made, you'll need to start another PR since the merge process is largely automated

@e111077 No I just wanted to say this solution works in the case where catalog is removed from workspaces and has its own node_modules directory.
Accepting this change in the current state of this repo will actually have no effect, it's still good for prevention though.

IMO yesterday @augustjk's PR ( #4501) is a better solution but one needs to be aware it only works if package-lock.json is removed before npm i.
