docs: Add the repack config filename onto the base output directory.
  
      This allows us to repack lots of different configs to the same installer
      name and still be able to distinguish them.

        base_dir: output directory string
        config_filename: the secondary config filename string
  
      Returns:
        String to be used as output directory for this repack.
