Sends a critical PagerDuty alert, e.g. on action failure.

1. Create a service integration in PagerDuty:
   1. Go to PagerDuty > "Services" > Pick your service > "Integrations" > "Add a new integration"
   2. Choose a name (e.g. "Your GitHub CI/CD") and "Use our API directly" with "Events API v2"
   3. Copy the integration key
2. Set up a secret in your GitHub repo to store the integration key, e.g. "PAGERDUTY_INTEGRATION_KEY"
