      A utility to add some content inside a given text.
  
      Args:
         text (`str`): The text in which we want to insert some content.
         content (`str`): The content to add.
         add_after (`str` or `Pattern`):
             The pattern to test on a line of `text`, the new content is added after the first instance matching it.
         add_before (`str` or `Pattern`):
             The pattern to test on a line of `text`, the new content is added before the first instance matching it.
         exact_match (`bool`, *optional*, defaults to `False`):
             A line is considered a match with `add_after` or `add_before` if it matches exactly when `exact_match=True`,
             otherwise, if `add_after`/`add_before` is present in the line.
  
      <Tip warning={true}>
  
      The arguments `add_after` and `add_before` are mutually exclusive, and one exactly needs to be provided.

          `str`: The text with the new content added if a match was found.
