docs: Update DeployAzureResources.md with current GPT model details

Replaced outdated GPT-4-32k reference with GPT-4o, which is now used in the deployment. 
Also added a note that GPT models may be retired over time, and recommend checking Azure OpenAI model availability regularly to avoid deployment issues.
