Migrate to Flatpak pre-install

[danirabbit]

What Happened?

Currently we're using deb packages to pull in flatpak packages so that we have a way to manage removing or changing them

Steps to Reproduce

Check packages for:

• [ ] calculator
• [ ] camera
• [ ] document viewer
• [ ] fonts
• [ ] file-roller
• [ ] maps
• [ ] music
• [ ] screenshot
• [ ] videos
• [ ] web

Expected Behavior

We should migrate these to flatpak pre-install: https://docs.flatpak.org/en/latest/flatpak-command-reference.html#flatpak-preinstall

I wonder if this should be shipped in default-settings actually
