[BUG] Scenarios/AKS-OpenAI-CogServe-Redis-Embeddings : text-davinci-002

[khowling]

Describe the bug
bicep deployment fails with :

{"code": "DeploymentModelNotSupported", "message": "Creating account deployment is not supported by the model 'text-davinci-002'. This is usually because there are better models available for the similar functionality."}

Appears to be this issue ("likely related to the OpenAI deprecation announcements. I'm testing to see if gpt3-turbo can be used instead"):
