Update keyboard shortcuts script to show all runtime keybinds (#70)

* feat: Add a keyboard shortcuts helper

This commit:

* Changes keybinds to use `bindd` and adds descriptions for each one
* Changes the keybinds script to use `hyprctl binds` to inspect runtime keybinds
and generate a wofi menu to search/inspect keybinds

* Rely on 'order defined' for sorting

Using `hyprctl binds` lets us get the binds in the order they're
defined. This lets us be deliberate about what keybinds we want to show
up at the top of the presented window.

* Skip cache file for keybinds

* Strip extra newline causing double spacing
