iOS 16 added API toolbar(_:for:) equivalent to hidesBottomBarWhenPushed.
TabView and NavigationView of SwiftUI components have not ability to hide/show tab bar when push to next view like hidesBottomBarWhenPushed property in UIKit.
This example bring back that ability to SwiftUI app, but I'm not recommended use this code because usual navigation by NavigationLink will probably broken when NavigationView and NavigationLink get out of dependence on UIKit in the future OS version.
