Fix ResetPackageAsync throwing NotImplementedException

[Copilot]

Issue

The Microsoft.Windows.Management.Deployment.PackageDeploymentManager.ResetPackageAsync() method was throwing a System.NotImplementedException even though the underlying implementation exists. This was happening because the feature check IsPackageDeploymentFeatureSupported(PackageDeploymentFeature.ResetPackage) was hardcoded to always return false.

Changes

Modified the IsPackageDeploymentFeatureSupported method to properly check if the ResetPackage feature is available using PackageManagement_IsFeatureSupported instead of returning a hardcoded false.

case winrt::Microsoft::Windows::Management::Deployment::PackageDeploymentFeature::ResetPackage:
{
-    //TODO Awaiting Windows update
-    //return ::WindowsVersion::IsExportPresent(L"appxdeploymentclient.dll", "MsixResetPackageAsync");
-    return false;
+    BOOL isSupported{};
+    const HRESULT hr{ PackageManagement_IsFeatureSupported(L"ResetPackage", &isSupported) };
+    if (hr == E_NOTIMPL)
+    {
+        return false;
+    }
+    THROW_IF_FAILED_MSG(hr, "ResetPackage");
+    return !!isSupported;
}

This change allows the ResetPackageAsync method to properly determine if the feature is available on the current system instead of always throwing an exception. The implementation now follows the same pattern used by other feature checks in the same class.

Fixes #3.
