[Retros] One more typo

There is also a typo in the FEN for Typ B RxP. One row is 1RP4 when I
suppose it should be 1RP5.

All the other last move FENs at least parse correctly (html -> excel ->
text file -> epd2diag).

None of them are broken due to DR (quick 3 sec scan of each diagram
suffices).

Looking at them, the convention seems to be that White moved last. Odd. OK,
consider mine flipped.
