docs: Convert one entry lists to the scalar value
  
      This step is necessary because anchors are not kept for scalar values - just for lists and dictionaries.
      Now that we are done with all of our anchor references, we can convert these single entry lists to
      just the scalar entry, which is more usable.
  
      Some notes on anchors in ruamel.yaml are here: https://stackoverflow.com/a/48559644
  
      Args:
          config: The dict-like configuration from ruamel.yaml which should be simplified.
      Returns:
          The updated configuration.
