在Windows 11下，使用WinUI2.6以上版本的ListView长这样：
然而到了Win10上，尽管其他控件的样式没有改变，但ListViewItem变成了默认样式（初代Fluent）
最重大的问题是，Win10上的HorizontalAlignment未被设置成Stretch，可能造成严重的UI错位（隔壁livelyweather也有这个问题）。
这疑似是Win10上未使用正确的资源造成的。
为了解决此问题，我们可以在App.xaml中的App.Resources中添加以下样式（从VS Blender复制），并将其作为ListViewItem的默认样式即可
注：此处使用了条件XAML语句，这样在Win11上就可以使用自带的样式（似乎多一点动画），将contract13NotPresent删去问题也不大
