Fix GNOME Install For Ubuntu 20.04 (#6)

* If we're gonig to exit then we should be more sure about our messaging.

* Only have GIMP installed from Flatpak.

* Playbook is causing Ubuntu 20.04 to fail.

* Define gnome_install.failed since some Ansible versions are picky.

* Try again for mad non-Parrot versions of Ansible.

* Add debug.

* Still trying to make Ubuntu 20.04's Ansible happy.

* Fix typos.

* Ubuntu does not need to install Dash To Dock. Also ensure `make` is installed on other distros so that the project is compiled.

* Remove debug.
