"Custom Bar Color" playground not working

[dfabulich]

The Skip Showcase Toolbar playground includes a bunch of playgrounds to set the .toolbarBackground for the .tabBar, e.g. .toolbarBackground(.blue, for: .navigationBar, .tabBar)

These have no effect in SkipUI 1.52. (I think the Nav 3 changes may have broken this.)

I mentioned in skiptools/skipapp-showcase#94 that this playground doesn't work in iOS 26, either.

But, I guess we should still fix it for Android at least, as @aabewhite pointed out.
