fix: ball_maze instruction typo (roles -> rolls) and pour_marbles pouring direction in instruction

ball_maze: 'roles' -> 'rolls'. pour_marbles: one task per pouring direction (from source_cup in the raw data); per-frame task_index, episode tasks/stats, stats.json and total_tasks updated. Frames and videos unchanged.
