[Microsoft.Compute/disks]: "securityDataUri" missing in "CreationData"

### Resource Type

Microsoft.Compute/disks

### Api Version

2021-04-01

### Issue Type

Missing property(s)

### Other Notes

CreateOption "ImportSecure" creates a disk from a VHD and VMGS files in blob storage. The VMGS file should be passed in through "securityDataUri" propoerty.

I get a warning:
> The property "securityDataUri" is not allowed on objects of type "CreationData". Permissible properties include "galleryImageReference", "imageReference", "logicalSectorSize", "sourceResourceId", "uploadSizeBytes". If this is a resource type definition inaccuracy, report it using https://aka.ms/bicep-type-issues.bicep[BCP037](https://aka.ms/bicep/core-diagnostics#BCP037)

### Bicep Repro

}]

### Confirm

- [x] I have read the troubleshooting guide and looked for duplicates.

Start by locating the Microsoft.Compute/disks 2021-04-01 CreationData definition in the type definitions and compare its permitted properties with the Azure API behavior described. Done means the securityDataUri property is accepted for ImportSecure alongside the other listed CreationData properties.
