Fixes:#9974After updating the `DotnetPack` test to use:    proj.OtherBuildItems.Add (new AndroidItem.AndroidMavenLibrary ("org.jetbrains.kotlinx:kotlinx-serialization-json-jvm") {        MetadataValues = "Version=1.3.3;Bind=false",        BinaryContent = () => [],    });And then seeing the `.jar` files inside:    using var aarStream = new MemoryStream ();    var aarEntry = nupkg.ReadEntry (aarPath);    aarEntry.Extract (aarStream);    aarStream.Seek (0, SeekOrigin.Begin);    using var aar = ZipArchive.Open (aarStream);    int count = aar.Count (e =>        e.FullName.StartsWith ("libs/", StringComparison.OrdinalIgnoreCase) &&        e.FullName.EndsWith (".jar", StringComparison.OrdinalIgnoreCase));There were originally 0 files, when there *should* be 2!Reviewing the `.binlog`, `dotnet pack` has an inner/outer build goingon during it:* `_WalkEachTargetPerFramework` target* Runs `<MSBuild/>`, the `_GetFrameworkAssemblyReferences` target* Which calls our `_CreateAar` target.If `_CreateAar` can be called in this scenario, it needs to depend on`_CategorizeAndroidLibraries`, so none of its inputs are missing.With this change, the test now asserts that 2 "hashed `.jar` files arepresent in the `.nupkg` output.
