Unable to select Sonnet 3.7 in model dropdown

[uzaidnasir28]

Describe the bug
I have the latest version of copilot.. in my github settings i have enabled sonnet 3.7 but when i try to select models in CopilotForXcode chat it doesnt give me that option.

Versions

• Copilot for Xcode: 0.32.0
• Xcode: 16.2
• macOS: 15.3.1

Steps to reproduce

1. Enabled Sonnet 3.7 in github Anthropic Claude 3.7 Sonnet in Copilot
2. Not available in plugin for xcode.
   NOTE - I am able to access Claude 3.7 Sonnet using my github account and vscode..

so its only not working in CopilotForXcode

The issue persists in version 0.33.0 for different models. There is a mismatch between the models I can enable in my Copilot settings and the models show in the chat window.
