bugfix: add `?api-version` parameter to all chat message requests for Azure OpenAI

[cdxker]

Description

Azure OpenAI compatibility requires that all chat completion messages support include an api-version request parameter. Include a default api-version request parameter at the end of all messages.

Need to also ensure that this does not break compatibility with non-azure open-ai routes
Test with:

• openai
• openrouter
• litellm
