fix: tilføj Flathub remote og ret pakkelister

- Tilføj Flathub remote-task inden Flatpak-install (manglede på ny installation)
- Ret nvim → neovim og fjern mangojuice fra DNF i vars og manual guide
- Tilføj mangojuice som Flatpak (io.github.radiolamp.mangojuice)
- Opdater README og fedora-kde-setup med Flathub-trin
