Fix copy-paste bug: targetSdkVersion gated on MinSdkVersion in CreateDynamicFeatureManifest

[Copilot]

In CreateDynamicFeatureManifest.GenerateFeatureManifest, both the minSdkVersion and targetSdkVersion attributes were guarded by !MinSdkVersion.IsNullOrEmpty() — a copy-paste error. This caused targetSdkVersion to be silently omitted when MinSdkVersion was empty, and threw ArgumentNullException when MinSdkVersion was set but TargetSdkVersion was null.

Change

Gate targetSdkVersion on TargetSdkVersion:

// Before
if (!MinSdkVersion.IsNullOrEmpty ())
    usesSdk.Add (new XAttribute (androidNS + "minSdkVersion", MinSdkVersion));
if (!MinSdkVersion.IsNullOrEmpty ())   // ← wrong variable
    usesSdk.Add (new XAttribute (androidNS + "targetSdkVersion", TargetSdkVersion));

// After
if (!MinSdkVersion.IsNullOrEmpty ())
    usesSdk.Add (new XAttribute (androidNS + "minSdkVersion", MinSdkVersion));
if (!TargetSdkVersion.IsNullOrEmpty ())
    usesSdk.Add (new XAttribute (androidNS + "targetSdkVersion", TargetSdkVersion));

Pull request overview

Fixes a logic bug in CreateDynamicFeatureManifest.GenerateFeatureManifest where emitting the targetSdkVersion manifest attribute was incorrectly gated on MinSdkVersion (copy/paste mistake). This ensures targetSdkVersion is produced when provided and avoids ArgumentNullException when only MinSdkVersion is set.

Changes:

• Gate uses-sdk/@android:targetSdkVersion emission on TargetSdkVersion instead of MinSdkVersion.
