docs: Consolidate the provided arguments.
  
          If the provided arguments have matching options, this performs a type conversion.
          For any option that has a default value and is not present in the provided
          arguments, the default value is added.
  
          Args:
              args (dict): A dictionary of the provided arguments.
  
          Returns:
              dict: A dictionary with the type converted and with default options enriched
                    arguments.
