in #2529 @simon-mo introduce some python typing syntax, which is not compatible in python3.8 like TypeTokenIDs = list[int] in https://github.com/vllm-project/vllm/blob/93b38bea5dd03e1b140ca997dfaadef86f8f1855/vllm/entrypoints/openai/serving_completion.py#L22C1-L22C25 which should be TypeTokenIDs=List[int] in python3.8. could you please fix it?
