Onboarding additional model providers with GitHub Copilot for Claude Sonnet models in public preview

Starting Tuesday, March 11th, GitHub will onboard Google Cloud Platform and Anthropic PBC as providers of the public preview models Claude 3.5 Sonnet and Claude 3.7 Sonnet.

This change will result in increased Claude Sonnet rate limits and greater service quality in GitHub Copilot when using these models.
