* fix(user-setup): Locally install Flathub repo
This uses the existing Flathub repo file in /etc/flatpak/remotes.d so that it can be added completely offline
* chore(flatpak-system-install): Remove Fedora system flatpakrepo
* fix: Stop caching flatpaks
These take up way too much space in images
* fix(flatpak-system-install): Require network connection
* fix(flatpak-system-install): Restart on failure
* fix(gnome): Add Silverblue flatpaks to install list
* fix(flatpak-system-install): Silence errors on package removal
A package may not be removed for a number of reasons, for example if someone were
to rebase from Kinoite to Bazzite GNOME, they wouldn't have the GNOME app suite
installed from Silverblue
* fix(deck): Don't try to install cached system flatpaks
