A Fedora Silverblue post installation menu script

This is WIP! More features to be added and a lot of code cleanup and compartmentalization.

Fedora Silverblue is an 'immutable' Linux distribution.
This means we heavily relly on flatpaks for our GUI applications and containers (toolbox) for our terminal based applications.

A few notes

This post-install script provides a menu and an easy to use experience. You just press a number and enter.
The script will apply all the configuration I do on my Fedora Silverblue installs.
