[Bug] Incorrect link to pinecone-datasets generation

[eekaiboon]

Is this a new bug?

• [X] I believe this is a new bug
• [X] I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

Verbatim from langchain-retrieval-augmentation.ipynb:

We will download a pre-embedding dataset from pinecone-datasets. Allowing us to skip the embedding and preprocessing steps, if you'd rather work through those steps you can find the [full notebook here](https://colab.research.google.com/github/pinecone-io/examples/blob/master/docs/langchain-retrieval-augmentation.ipynb).

The full notebook here link does not point to a reference which explains how pinecone-datasets was embedded and preprocessed.

Personally, I would like to learn how to embed webpages of documentation (e.g. LangChain Docs) for retrieval augmentation use case. Thank you for your attention!

Expected Behavior

The full notebook here link correctly point to a reference which explains how pinecone-datasets was embedded and preprocessed.

Steps To Reproduce

1. Go to langchain-retrieval-augmentation.ipynb under the Building the Knowledge Base section
2. Click on the full notebook here link
3. You will see that the link does not bring you to a reference that explains how pinecone-datasets was embedded and preprocessed
