docs: Parse the "personalities" line of ``/proc/mdstat``.
  
      Lines are expected to be like:
  
          Personalities : [linear] [raid0] [raid1] [raid5] [raid4] [raid6]
  
      If they do not have this format, an error will be raised since it
      would be considered an unexpected parsing error.
  
      Parameters
      ----------
  
      personalities_line : str
          A single "Personalities" line from an ``/proc/mdstat`` files.
  
      Returns
      -------
          A list of raid "personalities" listed on the line.
