Cancelled GitHub CI rerun after success is treated as failure

PR: https://github.com/nodejs/node/pull/43085
Action rerun attempt: https://github.com/nodejs/node/actions/runs/2320332585/attempts/7
git-node land output: https://github.com/nodejs/node/pull/43085#issuecomment-1126858386

At the moment of landing, the latest run of that action was cancelled, there were 5 prior successful runs, and GitHub UI reported everything as green.
However, ncu treated it as Last GitHub CI failed error, which is either wrong (not sure if easily fixable, as it requires failproof checking previous attempts) or confusing (Last GitHub CI cancelled might be a better error message).

Details: in PRChecker.checkGitHubCI(), commit.checkSuites.nodes[2] for this case was

  {
    app: { slug: 'github-actions' },
    conclusion: 'CANCELLED',
    status: 'COMPLETED'
  }

Comienza en PRChecker.checkGitHubCI() e inspecciona cómo se interpreta commit.checkSuites.nodes, usando el PR vinculado, el intento de la acción y la salida de git-node land como contexto de reproducción. Verifica el comportamiento cuando la ejecución más reciente de GitHub Actions se cancela después de ejecuciones anteriores exitosas. Se considera terminado cuando el estado de CI informado y el mensaje de error reflejan correctamente ese caso, con pruebas que lo cubran.
