Ali Waseem db281bd1d1 feat: alert in Slack when master breaks (#44456) ...

## Summary
- Adds a new GitHub Actions workflow that sends a Slack alert when
Studio E2E tests or unit tests fail on master
- Uses `workflow_run` trigger so no changes needed to existing CI
workflows
- Reuses the existing `SLACK_DASHBOARD_WEBHOOK_URL` secret

Closes FE-2883
