[Bug]: The sample code for integrating langchain in the 2.4.x Docs has the problem of referencing the wrong package.

[xxh18819431660]

Is there an existing issue for this?

• [ ] I have searched the existing issues

Environment

- Milvus version: 2.4.x
- Deployment mode(standalone or cluster): standalone 
- MQ type(rocksmq, pulsar or kafka): None   
- SDK version(e.g. pymilvus v2.0.0rc2): None
- OS(Ubuntu or CentOS): None
- CPU/Memory: None
- GPU: None
- Others: None

Current Behavior

When I refer to the docs of version 2.4.x and run the sample code of Question Answering over Documents with Milvus and LangChain, I find that the code runs with this error: NameError: name 'PromptTemplate' is not defined The specific error location is in run of the Ask your question code. The specific code israg_prompt = PromptTemplate.from_template(template). https://milvus.io/docs/integrate_with_langchain.md#Ask-your-question

Expected Behavior

I sincerely hope that the committers can change this code in https://milvus.io/docs/integrate_with_langchain.md#Prepare-data: from langchain_core.prompts import ChatPromptTemplate to from langchain_core.prompts import PromptTemplate In this way, no error will be reported when the package method is called later.
