[Alert] Do not ping On-Call for Dev URL Synthetic

[ph-One]

Summary

We have two alerts surrounding dev URL availability with varying alert chains. Remove the Cloudwatch alert and update the Datadog monitor to alert to #devops-alerts

Notes

• CIT was a spike team that is no longer together
• Datadog Monitor
  • https://vagov.ddog-gov.com/synthetics/details/ax4-fak-qa8
  • https://github.com/department-of-veterans-affairs/devops/blob/master/terraform/environments/datadog/cit.tf
• Cloudwatch Monitor
  • https://github.com/department-of-veterans-affairs/devops/blob/master/terraform/environments/dsva-vetsgov-ew-utility/cloudwatch.tf
• Development environments are designed for ongoing development and breakage
• The #oncall channel is for urgent and immediately actionable items

Acceptance Criteria

• [ ] Cloudwatch alert has been removed
• [ ] Datadog synthetic is alerting #devops-alert
