Import demo apps from apertis-flatdeb-demo (!4) · Merge requests · infrastructure / Apertis Flatpak Runtime

This MR migrates the contents of apertis-flatdeb-demo to this repo so we have a single repo for all flatpak/flatdeb work in Apertis.

It includes !3 (merged) and adds the following:

make the pipeline more generic by not hardcoding the runtimes and apps IDs
add jobs for building and publishing demo apps
import existing runtime and demo app from apertis-flatdeb-demo
improve the GNOME Font Viewer demo app by ensuring its icon and .desktop file are properly exported
add back the curl demo app and ensure it can build on our infra

Note: untested in its current form due to gitlab downtime!
