Remove pos.capture_or_promotion() This patch replaces `pos.capture_or_promotion()` with `pos.capture()` and comes after a few attempts with elo-gaining bounds, two of which failed yellow at LTC (https://tests.stockfishchess.org/tests/view/622f8f0cc9e950cbfc237024 and https://tests.stockfishchess.org/tests/view/62319a8bb3b498ba71a6b2dc).
