o1/o3-mini models fail with temperature parameter not supported error

[Ziyann]

When attempting to use the o1/o3-mini models with the plugin, requests fail with a 400 error due to the temperature parameter being unsupported.

Steps to reproduce:

1. Configure the plugin with gptModel = o1 or gptModel = o3-mini
2. Submit a code review request
3. Request fails with HTTP 400 (see error below)

Error response:

{
  "error": {
    "message": "Unsupported parameter: 'temperature' is not supported with this model.",
    "type": "invalid_request_error",
    "param": "temperature",
    "code": "unsupported_parameter"
  }
}

Workaround: Removing the temperature parameter from the request allows the o1/o3-mini models to work properly.

I've done some quick testing in stateless mode after implementing the workaround, and the o1/o3-mini models seems to perform pretty well for code reviews - noticeably better than 4o in my limited testing.

Also, exposing the reasoning_effort parameter might be a good idea for these models.

@Ziyann for patches we are using gerrithub. We are working now back to the plugin
