Show icons in selector

[martinheidegger]

Currently the icons are not shown in the selector.

card/src/components/docs/card/CardForm.tsx

Lines 134 to 138 in ab447c7

	<SelectGroupWithLabel
	groups={CountryGroups as OptionGroup[]}
	name="bottom1"
	label="Icon A"
	>

It would be nice to have some way to show the icon when selecting.
