Proposed fix: [Vercel CLI] 'No existing credentials found. Please run vercel login or pass --token' in CI

Option: Pass a token [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. vercel pull --yes --token $VERCEL_TOKEN
2. vercel deploy --token $VERCEL_TOKEN
Expected: Command proceeds without the error.
