• #9788 82080b5 Thanks @SkrOYC! - fix: handle "tool_call" content blocks in ChatGoogleGenerativeAI with outputVersion: "v1"

  Previously, using outputVersion: "v1" with ChatGoogleGenerativeAI would throw an "Unknown content type tool_call" error when processing tool calls generated by LangChain's AIMessage. This fix adds a handler for the tool_call block type in the conversion utility, ensuring compatibility with standard LangChain tool call blocks.
