Missing "await" and "async" keywords in jsx and JavaScript lexers

[jmooring]

The await and async keywords are missing from the JSX and JavaScript lexers.

Raw text:

class UserProvider extends React.Component {
  state = { user: null };

  async componentDidMount() {
    const user = await fetchUser();
    this.setState({ user });
  }

  render() {
    return this.props.render(this.state.user);
  }
}
