[evince/wip/gpoo/image-rebuild] ci: Install docker to rebuild image

[Germán Poo-Caamaño <gpoo src gnome org>]

    ci: Install docker to rebuild image
    
    * Add a CI stage to rebuild the CI image and update Gitlab's
      registry.
    * Change the tag to use :latest instead of :poppler. Thus, future
      rebuilds will not need manual intervention (or reduce it at least).
    * Use Alpine to build the image, as it is small and it only requires
      buildah and runc.
