Configure integration workflow for authenticated API requests

The `arduino/compile-sketches` GitHub Actions action queries the GitHub API for the base ref of the pull request, which
is used for the memory deltas determination.

GitHub does rate limiting of API requests and if the limit is exceeded, a spurious failure of the workflow run will
occur.

Authenticated API requests are given a more generous API request allowance, so providing the action with the
automatically generated GitHub access token stored in `secrets.GITHUB_TOKEN` to use for the API requests should prevent
any such workflow run failures.
