Constrained output tokens specification

Hello,

I wanted to bring your attention to that in this script: https://github.com/SALT-NLP/LLMs_for_CSS/blob/main/test_official_chat_css.py, there is a bug on line 211 - the parameter on huggingface is called **force_words_ids,** and not **force_word_ids** (as can be found in https://huggingface.co/docs/transformers/main_classes/text_generation).

Best regards,
