Subject: [PATCH] ADFA-6371: Make the selected toggle button visible in
 new-file dialogs

Material 3 fills a checked outlined button with colorSecondaryContainer,
which the theme sets to #E8E8E8 on a #EDEDED dialog, and keeps the text
colour, so selecting Kotlin or a class type showed no change. The theme
now points materialButtonOutlinedStyle at a style that fills checked
buttons with colorPrimary and draws their text and icon in
colorOnPrimary; unchecked and non-toggle buttons keep Material's colours.

The Class button also switches to the Kotlin icon when Kotlin is picked.
