[Fix] Align assistant_message structure in camel with OpenAI Chat API specification

[LuoPengcheng12138]

It seems that the structure of assistant_message in camel is inconsistent with the OpenAI API documentation (https://platform.openai.com/docs/api-reference/chat/create):

In camel/messages/base.py, the construction code of assistant_message is as follows:

@classmethod
def make_assistant_message(
    cls,
    role_name: str,
    content: str,
    meta_dict: Optional[Dict[str, str]] = None,
    video_bytes: Optional[bytes] = None,
    image_list: Optional[List[Union[Image.Image, str]]] = None,
    image_detail: Union[
        OpenAIVisionDetailType, str
    ] = OpenAIVisionDetailType.AUTO,
    video_detail: Union[
        OpenAIVisionDetailType, str
    ] = OpenAIVisionDetailType.LOW,
) -> "BaseMessage":

While the parameters specified in the API documentation are as follows:
