The "use" attribute should also work for variants.

Problem/Motivation

If the markup of a variant is too differnt from another variant it often makes sense to put the markup in own template file.
Right now it is only possible to assign one template to pattern using the "use" attribute.

card:
  label: "Card"
  use: "@molecules/card/card.twig"
  variants:
    default:
      label: Default
    horizontal:
      label: Horizontal
      use: "@molecules/card/card--horizontal.twig"

Proposed resolution

Add the possibilitly to assign a template to a variant.
