    ci: Use v3 of the Docker image for CI builds
    
    Don’t update to the full CI setup from master, since its success depends
    on other fixes which are only present in master. However, using v1 of
    the Docker image is no longer possible since it’s been removed from the
    registry. Using v3 should enable CI builds for glib-2-56 to succeed.
