Add testResult for purge-protection deployment

Captured from successful deployment of the updated main.bicep:
- correlationId: 08a19c7d-365d-455d-bbac-4de41d42a718
- deploymentName: kvc-deploy-2b2b8b3f
- region: eastus

Per the contribution guide, any change to a .bicep or .json template
must be re-deployed and the testResult section of metadata.json
updated so the maintainer's /verify workflow can confirm the
deployment hash matches the template in the PR.
