Chess puzzles write move number as #Some(23)

The lichess puzzle db at https://database.lichess.org/#puzzles does not follow the specified format. Instead of encoding puzzles with the move number as in the example:

The move number is written as

Note the "#Some(47)" etc.

I believe this is an error caused by the fact that this line

https://github.com/lichess-org/database/blob/690c473edf12c03fbd8e2ec5956297b75e552870/src/main/scala/Puzzles.scala#L80

calls readPly which returns an Option[Ply] (https://github.com/lichess-org/scalachess/blob/6cffb30ecf55b9859263bb150cafb7812e6180ef/src/main/scala/format/FenReader.scala#L99) and so serializing it results in Some in the URL.
