Update the Waybar keyboard module to move the keyboard layout to the tooltip when hovering over the module (and out of the actual Waybar).
This will contribute to a cleaner look, and help trim down the lengthiness of the Waybar without sacrificing the utility of the module.
* Move keyboard layout to tooltip
* The module comments also referenced a script for sending signal, but there is no such script. The comments have been updated to reference example code added to ~/.config/sway/config.d/input
In addition to adding the example code, ~/.config/sway/config.d/input itself was updated to address some issues and add additional functionality.
* Remove the note about finding the touchpad ID and adding it to the config. This has not been necessary on Sway for a long time.
* Remove the `input type:keyboard xkb_layout "us"` line. This line is not actually doing anything since it will be overwritten by the `exec_always` block right below it every time Sway is reloaded.
* Enable numlock by default
* Add a commented block with example config for setting up keyboard layout toggle.
* Add explanatory comments.
