Backport Auto Label workflow fails with "Cannot find module '@actions/github'"

[Yicong-Huang]

What happened?

The Backport Auto Label workflow (.github/workflows/backport-auto-label.yml) fails on every PR into main. Its github-script step calls require("@actions/github") to build a second Octokit, but github-script's patched require resolves modules relative to the checked-out workspace — which has no such package — so the step aborts with Cannot find module '@actions/github'. Expected: the step labels fix: PRs and posts its report as before.

How to reproduce?

1. Open or edit any PR targeting main.
2. Watch the Backport Auto Label check.
3. It fails at the "Label fix PRs and request release-manager review" step.
