Add support for List Supported AI Provider Models method

The Crowdin API has been extended with a new endpoint, allowing you to retrieve the list of supported AI models for a specific AI provider in your [AI](https://support.crowdin.com/developer/api/v2/#tag/AI) workflow.

The Crowdin API client libraries need to be updated to include this new endpoint.
