SwiftUI: Fix toolbar buttons not fully tappable in iOS 26

In iOS 26, you may find that some of your toolbar items can only be tapped exactly on the icon itself rather than the whole padded button. To fix this, use a Label for your buttons instead of just an Image. This is also superior than only an image anyway, as it adds text labeling and accessibility.
ToolbarItem {
Button(action: {}, label: {
Label("Like", systemImage: "heart").labelStyle(.iconOnly)
})
}
