Button - enhancement to allow pass extra content

[daniele-zurico]

In the stories/Button/ClassBased.stories.js is good to have as well documented... something easy that maybe will make the label bold:

/**
* button allow to pass a simple value or if needed a custom one as children property
*/
export const CustomContent = {
  args: {
    label: 'Button',
    children: [
      <strong>login</strong>,
    ],
  },
};
and the same thing in the `design system section`

In design-system there is not ClassBased.stories, in which file?
