CI: Use tytan652/flatpak-github-actions image for Flatpak jobs

The actual Fedora-based image are not compatible with the action because
Fedora provides unstable version of flatpak-builder and a breakage
happened between two unstable version

This also means that the action is not completely compatible with
flatpak-builder 1.4

To solve this issue an alternative base image was proposed, but it is
not upstreamed yet, so my fork registry is used for now

Also flatpak-builder-lint is provided in the image so the related action
is modified to work with the provided version
