Is your feature request related to a problem? Please describe.
I can't find how to use YiVal with an Azure OpenAI LLM in the doc or github

Describe the solution you'd like
A clear example for using Azure OpenAI LLM

Describe alternatives you've considered
I've seen this page : (

YiVal/demo/tutorial_notebook/model_comparison.ipynb

Line 21 in 6cbf2b2

"|--------------| ---- | ---- | ---- |--------------|\n",

)
But the examples are for using a local model.

sadly I don't think it naturally support azure at this point. openai library and litellm library both deploy breaking updates compare to the current version that YiVal relies, and the version of litellm YiVal used for now does not support azure naturally
