CI: cache-deps: rm skip intended for master<->PR merge skip

This workflow it intended to be run on `master` only.
& to run after every merge to rebuid the cache, as was agreed before

While this using this skip action - means that if the same `workflow` was
present in the PR - the workflow would not run inside `master`, so:
1. this code is not needed in this workflow.
2. this code may work against the agenda of the workflow.

So, lets just simplify things here.
