Stepper: Add class for each step's icon

[ahoiroman]

Description

Hello everybody,

I'd love to see one feature:

The stepper can - at the moment - have a custom icon for each step. It would be super cool to allow each step to define it's own css class that is applied to the icon. This way, one could - for example - spin an icon to indicate that this step is currently worked on, while other steps do not spin, as they have not been started yet or have been finished already.

So maybe it would be possible like this:

 return {
    title:'foo',
    description: 'bar',
    icon: 'i-lucide-refresh-cw',
    class: 'animate-spin'
  }
