[nautilus/wip/oholy/ci-style-check: 87/88] ci: Use docker image to speed up jobs

[Ondrej Holy <oholy src gnome org>]

    ci: Use docker image to speed up jobs
    
    Fedora and style check jobs install dependencies on each run. This
    causes that the pipelines take a long time. Let's use a custom docker
    image to not block runners for such a long time and to get the pipeline
    results faster. This commit also adds a new job to generate the docker
    image for us.
