Fix YAML parsing errors in PR workflow files

- Replace multi-line JS template literals that had content at column 0
  in pr-validation.yml, pr-auto-tag.yml, and contributor-recognition.yml
  with single-line strings using \\n escape sequences
- Fix wrong label name 'good first issue' → 'good-first-issue' in
  contributor-recognition.yml to match the label defined in labels.yml
