fix(scripts): update flatpak only if command exists (#1000)

* fix(scripts): update flatpak only if command exists

Add a check to run flatpak update only when the flatpak command is
available, since Flatpak is not installed by default on Arch Linux,
preventing errors if flatpak is missing.

* Update scripts/runUpdates.sh
