-------------------------------------------------------------------
### Summary   
This pull request updates the way the GitHub Models API is called in
both the GitHub Actions workflow and the local test script. The main
focus is on switching to the new API endpoint and updating the model
identifier to the correct format.

**API Endpoint and Model Updates:**

* Changed the API endpoint from `models.inference.ai.azure.com` to
`models.github.ai/inference` in both
`.github/workflows/issue-triage.yml` and `test-triage-local.js` to use
the new GitHub Models service.

* Updated the model identifier from `"gpt-4.1"` to `"openai/gpt-4.1"` in
both files to match the expected model naming convention.

**Environment Variable Handling:**

* Added the `GITHUB_TOKEN` environment variable to the `Triage Analysis`
step in the workflow to ensure the token is available for API calls.
