Issue: pull_prompt include_model=True for ChatAnthropic model throws error when invoked

[ncnlinh]

Issue you'd like to raise.

Per title, the following code:

langsmith_client = Client()
prompt_with_model: RunnableSequence = langsmith_client.pull_prompt(prompt_id, include_model=True)
prompt_with_model.invoke(prompt_input)

throws this error:

anthropic.BadRequestError: Error code: 400 - {'type': 'error', 'error': {'type': 'invalid_request_error', 'message': 'tools.0.type: Extra inputs are not permitted'}}

I believe the tool is still in the format of OpenAI when pulled, and it has to do with this changeset: #1210.

Suggestion:

What I did so that it works:

langsmith_client = Client()
prompt_with_model: RunnableSequence = langsmith_client.pull_prompt(prompt_id, include_model=True)
if isinstance(prompt_with_model.last.bound, ChatAnthropic):
  # Rebind tools. For remote prompts with Anthropic, after pulling from hub, the tools are not bound correctly.
  rebound_llm = prompt_with_model.steps[1]
  prompt_with_model = RunnableSequence(
    prompt_with_model.first,
    rebound_llm.bind_tools(rebound_llm.kwargs["tools"])
  )
prompt_with_model.invoke(prompt_input)

Could someone with more context (@hinthornw , @madams0013 or @agola11 ) take a look?
