CI: cache-deps: rm pull request hook (#2426)

* CI: cache-deps: rm pull request hook

I needed to remove
b0621d7
before merge.

That is my fault, I should be more conservative between draft<->mergable PR.

* CI: cache-deps: shift cache regeneration time

Since most contributors are in the US & EU, & lets pretend they contribute
between 17:00 - 00:30 - this cache time seems better.
