There have been some deprecation warnings during the build process (which I can't find right now). The action 'bilelmoussaoui/flatpak-github-actions@v4' probably is outdated and should be replaced by 'flatpak/flatpak-github-actions' but I'm just guessing here.

@Murmele : could you perhaps take a look at this?
