Add hint-class to the group and icon-class to menu items

<x-group hint-class> adds classes to the hint, as the text fields'
hint-class does, and a validation message still replaces the hint.
<x-menu-item icon-class> adds classes to the leading icon, for an icon
whose colour means something of its own, such as a sport's glyph.

A colour class there has to win over the component's own colour, and
which of two colour utilities wins depends on the order Tailwind emits
them (text-error comes before text-on-surface-variant). So when either
prop is given, the component's own colour is written with a :where()
variant that carries no specificity, as the fields' hint colour sits
in the components layer. A disabled item's icon stays disabled. Without
the props the markup is unchanged. The skill now also lists the fields'
hint-class, which it had left out.
