CI(Windows): pass GITHUB_TOKEN to compile prepack step to prevent GitHub API 403s

[Copilot]

The CI - Build - Windows compile job failed in vscode-min-prepack due to repeated unauthenticated GitHub API requests returning 403 (rate-limited). This PR wires token auth into the failing step so release-metadata fetches can complete under CI.

• Workflow change

  • Updated .github/workflows/ci-build-windows.yml in jobs.compile -> Build -> env to include GITHUB_TOKEN.

• Failure mode addressed

  • The prepack phase resolves upstream VS Code extension release tags via api.github.com; without auth, retries exhausted and the job exited non-zero.
