title: Define and apply theme on highcharts-react-official
body: <p>I'm trying to update <code>higcharts</code> texts font globally, I coundn't find anywhere on documentation how to apply a custom theme using <code>highcharts-react-official</code>. Is there an equivalent of <code>Highcharts.theme = style</code> and <code>Highcharts.setOption(Highcharts.theme)</code>?</p>
