reasoning model does not work #7127
Description
What happened?
当我在 model_info 中使用"family": "r1"的时候，如果是一个简单的 agent，可以输出think标签，但是当我在 agent 里面加入 tool 的时候，就无法输出think标签，终端会打印下面的内容：
/.venv/lib/python3.12/site-packages/autogen_ext/models/openai/_openai_client.py:1054: UserWarning: Could not find .. field in model response content. No thought was extracted.
thought, content = parse_r1_content(content)
下面是我的完整的代码：

我希望这个思考的过程是可以输出给我的
