• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

"convert_to_anthropic_tool" function within chat_models.py in the langchain_anthropic library needs to include adding "type" key in the formatted anthropic tool, just like what is happening in the open AI tool

Motivation

So that it can run through "create_react_agent" from langgraph like below:

agent_executor = create_react_agent(sonnet_3_5_model, [...], checkpointer=memory)

Proposal (If applicable)
