Resource type "Microsoft.VirtualMachineImages/imageTemplates@2024-02-01" does not have types available

**Bicep version**
Bicep CLI version 0.28.1 (ba1e9f8c1e)

**Describe the bug**
When using resource
`Microsoft.VirtualMachineImages/imageTemplates@2024-02-01`
You get the error Resource type "Microsoft.VirtualMachineImages/imageTemplates@2024-02-01" does not have types available.
However types exists https://github.com/Azure/bicep-types-az/tree/main/generated/imagebuilder/microsoft.virtualmachineimages/2024-02-01

**To Reproduce**
Try creating a imageTemplates resource with the 2024-02-01 API

Reproduce the issue by declaring a Microsoft.VirtualMachineImages/imageTemplates resource with API version 2024-02-01. Inspect the generated definitions under generated/imagebuilder/microsoft.virtualmachineimages/2024-02-01 and verify that Bicep can discover the resource types; done means the declaration no longer reports that types are unavailable.
