setup-msys2 saves the pacman package cache under a key ending in a hash of its contents. So with each update it saves more caches, what's more important it saves it per each PR ref. We don't want that. Keep only the msys2 cache on main branch and only the latest one per each configuration. If PR saves new one, it will be dropped, we prefer master branch case that can be used by all PR, rather then per PR cache of this. The few packages that will be refetched are ok. This change is an atempt to keep our cache under 10GB limit, to avoid evicting more important ccache caches.
