Error in Azure Portel Index: This index contains a vectorizer created by previous API versions that doesn't include the 'modelName' field. We recommend you to migrate by adding 'experimental' value automatically to the field to restore full portal functionality.

I have created index using the below sample.ipynb file:
https://github.com/Azure/azure-search-vector-samples/blob/main/demo-python/code/integrated-vectorization/azure-search-integrated-vectorization-sample.ipynb

And used the private preview azure search whl file: azure_search_documents-11.4.0b12 which was available on github, and recently removed from it.

So as per the below doc, we have a parameter model_name to add in azure_open_ai_parameters constructor:
https://learn.microsoft.com/en-us/python/api/azure-search-documents/azure.search.documents.indexes.models.azureopenaiparameters?view=azure-python-preview

I tried to add it in my script but I got below error:
**model_name is not a known attribute of class and will be ignored**

So I tried to upgrade the Azure Search Document sdk to 11.6.0.4b but still the issue is coming up.
Do we need to use some other whl file like we did earlier with 11.4.0b12 ?

Code snippet of my vectorizer:

```
vectorizers=[
AzureOpenAIVectorizer(
name="myOpenAI",
kind="azureOpenAI",
azure_open_ai_parameters=AzureOpenAIParameters(
resource_uri=os.getenv("AZURE_OPENAI_ENDPOINT"),
deployment_id=model,
model_name='text-embedding-3-large',
api_key=os.getenv("AZURE_OPENAI_API_KEY"),
),
),
]
```


I am using 2024-05-01-preview for openai version and text-embedding-3-large model.
Python version 3.8

Start with the integrated-vectorization sample.ipynb and the provided AzureOpenAIVectorizer snippet, then compare AzureOpenAIParameters behavior in azure-search-documents 11.6.0.4b with the linked preview documentation. Reproduce the model_name warning and verify the resulting index no longer reports the legacy vectorizer migration warning in the Azure portal.
