The straight forward way is to follow the .gitlint file from score repo: https://github.com/eclipse-score/score/blob/main/.gitlint

Update .github\actions\gitlint\action.yml:

      # Fetch the upstream .gitlint config from eclipse-score/score
      git clone --depth 1 https://github.com/eclipse-score/score.git /tmp/score-gitlint && \
      if ! gitlint --config /tmp/score-gitlint/.gitlint --commits origin/main..HEAD; then \
