Weird redirection in URL in `Advanced RAG on Hugging Face documentation using LangChain` cookbook

In [Advanced RAG on Hugging Face documentation using LangChain](https://huggingface.co/learn/cookbook/advanced_rag), there is a link in:

````
Method: split on different separators, use [semantic chunking](https://python.langchain.com/docs/modules/data_connection/document_transformers/semantic-chunker)…
````

when clicking it, the link is converted automatically to:

````
https://huggingface.co/docs/modules/data_connection/document_transformers/semantic-chunker
````

and ends up in a 404.

I don't know how to solve it since it seems like a problem with some routing (backend issue maybe?)

Start from the Advanced RAG on Hugging Face documentation using LangChain cookbook page and inspect the source containing the semantic chunking link. Compare the python.langchain.com URL with the automatically converted huggingface.co URL and check the relevant documentation link behavior. Done means the link no longer redirects to a 404 page.
