Gnome 48 support

[inducer]

Describe the bug
Many keyboard shortcuts stop working in Gnome 48. (Specifically, "window left" and "window right").

To Reproduce
Steps to reproduce the behavior:

1. Open two windows.
2. Hit Windows+Right arrow.
3. Observe an error on the gnome shell console and no window movement.

I was able to recover the functionality I care about by, um, editing these lines (in ~/.local/share/gnome-shell/extensions/[email protected]/keybindings.js)

PaperWM/keybindings.js

Lines 404 to 406 in 07214b0

	keyHandler = opensNavigator
	? asKeyHandler(Navigator.preview_navigate)
	: asKeyHandler(handler);

to read

keyHandler = asKeyHandler(handler);

I'm guessing this loses preview functionality, but 🤷 I don't want that anyhow, and it beats not being able to switch windows without a mouse. 🙂

Ah, dang. That doesn't seem to suffice. The window highlight switches, but then there's an assertion failure:

Mär 06 15:42:28 arc gnome-shell[3054]: meta_window_is_focusable: assertion '!window->unmanaging' failed

(And the new window does not get focused.)
