[addon-docs] Display HTML code for react storybooks

[inspiratweb]

Can we have a block like in the current addon-docs to display also the resulting plain html markup?
It would be very useful for design systems

Describe the solution you'd like
Using the text.stories given in the installation example we get the react code (in my case) like

() => <Button onClick={action('clicked')}>Hello Button</Button>

Is there a way to get the plain HTML from that code (not using addon-info)?

<button>Hello Button</button>
