docs: Return a protein variant, or "non-coding" for non-coding variant types
  
          CAUTION: Unlike other x_to_y methods that always return
          SequenceVariant instances, this method returns a string when
          the variant type is ``n``.  This is intended as a convenience,
          particularly when looping over ``relevant_transcripts``,
          projecting with ``g_to_t``, then desiring a protein
          representation for coding transcripts.
