hi!
When using the azure GPT endpoint, the --model CLI arg is ignored

So we should give a warning (or an error?) if the user tries using it.

(we instead get the model from: OPENAI_API_VERSION: '...')
see https://github.com/princeton-nlp/SWE-agent/blob/main/sweagent/agent/models.py#L247

(small correction: we get the model from AZURE_OPENAI_DEPLOYMENT)

Yup, this is not ideal. I remember this came up during the review of the PR. Let me revisit if we can't do better at some point (so leaving this open for now)
