code: def make_simple(data: Any) -> Any:
      
      return yaml.load(yaml.dump(data, Dumper=ruamel.yaml.RoundTripDumper), Loader=ruamel.yaml.Loader)
docs: Substitute all the references in the given data (typically a mapping or sequence) with the actual values.
      This is useful, if you loaded a yaml with RoundTripLoader and you need to dump part of it safely.
  
      :param data: data to be made simple (dict instead of CommentedMap etc.)
      :return: simplified data
