fix(wm): update monitor focus before focus-stack-window

This commit fixes the cases where you'd call this command on a monitor
which was not focused, for example by pressing a button on a bar like
komorebi-bar or other when you had focus on another monitor.
This change ensures that first we focus the monitor where the mouse cursor
is, this way it will act on the monitor that you've just pressed instead
of the monior that was focused before.
