de-serialization relies loading a pickle file need allow_dangerous_deserialization=True

[tpoisonooo]

I guess that is a version problem, see https://stackoverflow.com/questions/78120202/de-serialization-relies-loading-a-pickle-file and https://community.dataiku.com/t5/Setup-Configuration/When-using-RAG-in-Prompt-Studio-an-error-occurs/m-p/41636

Thanks for your contribution !

TypeError: __init__() got an unexpected keyword argument 'allow_dangerous_deserialization' 

Let me try to fix it, qaq~

This parameter requires langchain>=0.1.12, see https://api.python.langchain.com/en/latest/vectorstores/langchain_community.vectorstores.faiss.FAISS.html

so this PR merged here https://github.com/InternLM/HuixiangDou/pull/154
