Ubuntu Bicep doesn't build

### Issue Details

### Repro steps (*if necessary, delete otherwise*)
1. Follow https://learn.microsoft.com/en-us/azure/virtual-machines/linux/quick-create-bicep?tabs=PowerShell
2. Execute the bicep twice, on the second run it fails.

See discussions at https://github.com/Azure/bicep-types-az/issues/1687 .

Start with the Ubuntu Bicep quick-create guide linked in the issue and reproduce the deployment twice, then read the linked bicep-types discussion for context. Done means the same Bicep deployment succeeds on its second run without the reported build failure.
