Wrong description on Decorators

[MasahiroMorita]

In wiki page on storybook decorators, the example code is wrong:

const CenterDecorator = ({ children }) => (
  <div style={styles}>
    { children }
  </div>
);

storiesOf('Button', module)
  .addDecorator(CenterDecorator)
  .add('with text', () => (
    <Button onClick={action('clicked')}>Hello Button</Button>
  ))

this should be:

const CenterDecorator = (storyFn) => (
  <div style={styles}>
    { storyFn() }
  </div>
);
