IFTTT Deploy Notification for GitHub Actions

Add an IFTTT Webhooks notification job to a GitHub Actions workflow. Sends mobile push notifications on deploy success/failure.

Architecture

GitHub Actions workflow completes
  -> notify job (if: always())
    -> Collect job results from prior jobs
    -> Determine status string
    -> POST JSON to IFTTT Webhooks URL
      -> IFTTT triggers mobile push notification

The notification is silently skipped when the secret is not set, making it safe to add without requiring all contributors to configure IFTTT.
