Python: support Azure OpenAI Next generation API

[moonbox3]

According to the following API lifecycle doc, there will be support for preview features without having to roll the api-version each month:

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.getenv("AZURE_OPENAI_API_KEY"),
    base_url="https://YOUR-RESOURCE-NAME.openai.azure.com/openai/v1/",
    default_query={"api-version": "preview"}, 
)

response = client.responses.create(   
  model="gpt-4.1-nano", # Replace with your model deployment name 
  input="This is a test.",
)

print(response.model_dump_json(indent=2))
