DevEx/OpEx

We need the engineering team to be notified when the Automated Staging Test - Run integration tests action fails. The workflow is in .github/workflows/automated-staging-test-run.yml

Tasks

• [x] Look into adding people to notify using CODEOWNERS file
• [x] Look into adding a Slack Webhook to use in the workflow and notify the cdcti-alerts-nonprod slack channel
• [x] Loo into sending an email on test failure in the workflow
• [x] Decided to go with the Slack Webhook. Need to ask someone with Flexion Slack admin access to create it
