docs: Returns options with origin comments toggled. If this is enabled, the
  library generates comments for each setting based on the
  {@link ConfigValue#origin} of that setting's value. For example these
  comments might tell you which file a setting comes from.
  
  <p>
  {@code setOriginComments()} controls only these autogenerated
  "origin of this setting" comments, to toggle regular comments use
  {@link ConfigRenderOptions#setComments}.
  
  @param value
  true to include autogenerated setting-origin comments in the
  render
  @return options with origin comments toggled
