Unable to retrieve PrincipalId for resource: The property 'PrincipalId' cannot be found on this object.

### Description

Hello, I have a resource that is being retrieved with `Get-AzResource`. This is on an azure pipeline, as part of a role assignment for an azure app function.

I can see the `$resource.Identity.PrincipalId` when printing the Identity property, but when I get the PrincipalId property itself I get the following exception:
`System.Management.Automation.PropertyNotFoundException: The property 'PrincipalId' cannot be found on this object. Verify that the property exists.`

I can query the PrincipalId fine when examining the object from a local powershell instance, but the pipeline always fails for this resource.

Start by reproducing Get-AzResource with PowerShell 7.4.5 on Ubuntu and Az.Resources 4.4.0, using the resource response and failing PrincipalId access described here. Compare the returned Identity object and direct property behavior across the affected resource types; done means PrincipalId retrieval behaves consistently in the pipeline scenario.
