What this PR does:
This PR extends the TextArenaEnv class to support non-word-based TextArena games (like Tower of Hanoi) in addition to existing word-based games (like Wordle).

Problem:
The current TextArenaEnv implementation assumes all games have a word_list attribute, causing AttributeError when trying to load puzzle games like Tower of Hanoi that don't use words.

Solution:

• Added game_kwargs parameter to __init__ to pass game-specific configuration
• Modified ta_to_hf() method to check if environment has word_list attribute
• For word-based games: Uses existing logic with word_list
• For non-word-based games: Creates dataset with empty answers since puzzle games don't have predefined correct answers
• Updated env_response() to only set secret_word for games that have this concept

Testing:

• Verified Tower of Hanoi environment loads successfully
• Existing Wordle functionality remains unchanged
• Dataset creation works for both game types

Breaking Changes:
None - this is backward compatible with existing word-based games.
