What happened?

I'd like to import existing Azure KeyVault to my stack.
Import works correctly, but when I do a preview on just imported resources, I see the following change

~ sku : {
              ~ name: "Standard" => "standard"
            }

So Pulumi imports sku.name as Standard but the struct used to describe the sku name looks like

public static SkuName Standard { get; } = new SkuName("standard");
public static SkuName Premium { get; } = new SkuName("premium");

I'd expect no changes after successful import.

Steps to reproduce

1. Import existing Azure KeyVault to your stack
2. Execute pulumi preview

Expected Behavior

There should be no changes to apply.

Actual Behavior

Pulumi sees sku.name as updated.
