[Documentation]: Some github notebook links are broken

[MohammedRashad]

Documentation Issue Description

Hello,

I can see that due to structure changes in the github repo, some links are not pointing to anything, for exmaple here : https://docs.llamaindex.ai/en/stable/optimizing/advanced_retrieval/query_transformations/

The example notebook points to this link but has nothing : https://github.com/run-llama/llama_index/blob/main/examples/vector_indices/SimpleIndexDemo-multistep.ipynb

Colab is okay on the other side.

The broken link to the example notebook on the "Query Transformations in LlamaIndex" documentation page should be updated to:

https://gpt-index.readthedocs.io/en/latest/examples/query_transformations/SimpleIndexDemo-multistep.html

Additionally, other links in the documentation that need to be updated include:

• ./examples/query_transformations/HyDEQueryTransformDemo.html should be updated to https://docs.llamaindex.ai/en/stable/examples/query_transformations/HyDEQueryTransformDemo/
• ./examples/query_transformations/query_transform_cookbook.html should be updated to https://docs.llamaindex.ai/en/stable/examples/query_transformations/query_transform_cookbook/ ^[1][2].
