[Feature Request] Add shortcut to throw focused window to the fifth screen

[x-ji]

Now that Mac has been supporting maximum 5 displays for a while, it would make sense to add a shortcut to throw the focused window to the fifth screen. It seems that the current shortcut config supports up to 4 screens.

I can also give it a try if somebody helps to point me to the right direction 🙏 .

@x-ji take a look at HotKeyManager. It constructs the screen commands.
