docs: Render a template based on this TileBus Block.
  
          The template has access to all of the attributes of this block as a
          dictionary (the result of calling self.to_dict()).
  
          You can optionally render to a file by passing out_path.
  
          Args:
              template_name (str): The name of the template to load.  This must
                  be a file in config/templates inside this package
              out_path (str): An optional path of where to save the output
                  file, otherwise it is just returned as a string.
  
          Returns:
              string: The rendered template data.
