Fixes #6433.
Fix NullPointerException in PlayerRadarHud when switching servers by filtering null entities in getPlayers(). The crash occurs because mc.level.players() can return null entities during world transitions (e.g., when a StartConfigurationPacket is processed). Adding players.removeIf(entity -> entity == null) right after the addAll prevents the subsequent sort from calling position() on a null entity.
I checked the changed Java file with the available static check.
