    automation: use zypper dup in tumbleweed dockerfile
    
    The 'dup' command aligns the installed packages with the packages
    found in the enabled repositories, taking the repository priorities
    into account. Using this command is generally a safe thing to do.
    
    In the context of Tumbleweed using 'dup' is essential, because package
    versions might be downgraded, and package names occasionally change.
    Only 'dup' will do the correct thing in such cases.
