Removed pygbmodule, since manifest is now compiled-in

Figured out how to get it to work with the Ubuntu cross-compiler (it was in the Zephyr docs here).

install cmake from cmake-debs using .ci/scripts/install-cmake.sh

Went through the instructions to verify that it works with ubuntu:disco

Need to update these instructions for gpiod

sudo gpioset gpiochip0 0=1

Edit: done
