VMs stored in external drives show up as 0 KB

Another great release, working just fine on my M1 Air. Just one small thing. All my VMs are stored on my external SSD. UTM reports the size for all them as Zero KB...

Thanks @osy . A few hours ago, I discovered that it gets fixed when I remove the VMs from the list in UTM, and I re-add them one by one. Now it reports the size.

Edit: False alarm - Whenever I start UTM again, it's back to Zero KB.

@osy I think the problem is that the VM shortcut isn't accessed in the computeSize method, so resourceValues.totalFileSize returns nil.

UTM/Platform/UTMData.swift

Line 550 in ffa1586

guard let resourceValues = try? fileURL.resourceValues(forKeys: [.totalFileSizeKey]), let size = resourceValues.totalFileSize else {

I'm not sure how calling the vm.accessShortcut method should be called since that either needs async/await or a callback, and this method is called to be used as a property in SwiftUI.
