JSS example in documentation is buggy

[uadarsh]

Current example:

const {classes} = jss.createStyleSheet({
  '@keyframes bounce': bounce,
  bounce: {
    animationName: 'bounce',
    animationDuration: '1s',
  },
}).attach()

Corrected example:

const {classes} = jss.createStyleSheet({
  '@keyframes bounce': bounce,
  bounce: {
    animationName: '$bounce',
    animationDuration: '1s',
  },
}).attach()

$ sign in missing in animationName value.
