Get SMS Alerts with Twilio When GitHub Actions Fail

This workflow allows you to receive SMS alerts when a GitHub Action fails, by integrating Twilio's SMS service. The workflow is triggered on every push to the main branch and checks out the repository using `actions/checkout`. It then runs a simple "Hello World" script and builds an alert job that sends an SMS notification if the build action fails. The alert job uses the `twilio-labs/actions-sms` GitHub Action, which requires Twilio credentials to be stored as secrets in the repository settings. The message body of the alert includes the job ID and status for informational purposes. When a commit is made, the workflow triggers, and if the build action fails, an SMS notification is sent to the specified phone number.
