### Description
* I am trying to use tools with a local HuggingFace model.
* The [ChatHuggingFace](https://python.langchain.com/api_reference/huggingface/chat_models/langchain_huggingface.chat_models.huggingface.ChatHuggingFace.html#langchain_huggingface.chat_models.huggingface.ChatHuggingFace) documentation suggests that tools are supported, but the generated prompt does not include tools bound with `bind_tools`.
It's unclear if this is a documentation issue or just a mistake in the code. Since the HuggingFace tokenizer supports tool calling, I think it should be fairly easy to pass the tools to the tokenizer.
