Starting v0.10 [llama-index](https://github.com/run-llama/llama_index/releases/tag/v0.10.1) is split between llama_index and llama_index.core libraries. This commit updates documentation to work with llama-index v0.10 and higher. Also this commit adds note on how to run it with local llamaIndex model (like llama.cpp)
