ci(frontend): update licenses workflow dependencies and Node.js version (#4520)

# Description of Changes

- Added the workflow file itself
(`.github/workflows/frontend-licenses-update.yml`) to the trigger paths.
- Updated `step-security/harden-runner` from **v2.12.2** → **v2.13.1**.
- Bumped `actions/checkout` from **v4.2.2** → **v5.0.0**.  
- Upgraded `actions/setup-node` from **v4.1.0** (Node.js 18) →
**v5.0.0** (Node.js 22).
- Updated `actions/github-script` from **v7.0.1** → **v8.0.0**.  

These changes modernize the workflow, ensure compatibility with newer
Node.js versions, and keep GitHub Actions up to date.
