What changed

Updates the ARC quickstart to recommend GitHub App authentication for runner scale sets registered at the repository or organization level, while keeping the short setup example based on a classic PAT.

Also clarifies that runner scale sets registered at the enterprise level require classic PAT authentication, and aligns the GITHUB_PAT setup bullets with that token type.

Why

This addresses #37288 by nudging readers toward the more production-ready GitHub App authentication path where it is supported, while avoiding ambiguity for enterprise-level runner scale sets.

Testing

  • Ran npm run lint-content -- --paths content/actions/tutorials/use-actions-runner-controller/get-started.md
  • Pre-commit hook also ran npm run lint-content -- --precommit --paths C:/_Dev/Code/open-sources/docs/content/actions/tutorials/use-actions-runner-controller/get-started.md

Closes #37288
