No updates available for Store packages that are shown as upgradable

Brief description of your issue

Running winget upgrade lists two Store packages that it claims to be upgradable but when attempting to upgrade them it says there are no updates.

Steps to reproduce

Run winget upgrade:

Name                                 ID                                     Version  Verfügbar Quelle
------------------------------------------------------------------------------------------------------
Windows Community Toolkit Sample App Microsoft.UWPCommunityToolkitSampleApp 6.1.0.0  Latest    msstore
XAML Controls Gallery                Microsoft.XAMLControlsGallery          1.2.17.0 Latest    msstore

Now try to update one of these by running e.g.: winget upgrade Microsoft.UWPCommunityToolkitSampleApp:

Gefunden Windows Community Toolkit Sample App [Microsoft.UWPCommunityToolkitSampleApp]
Dieses Paket wird über den Microsoft Store bereitgestellt. “winget” muss das Paket möglicherweise im Auftrag des aktuellen Benutzers aus dem Microsoft Store abrufen.

Same output is shown for the other one.

Note that when searching for updates in the Store itself, no updates are listed for these apps.
