Storysource addon - allow prism configuration

Bug or support request summary

Have added Storysource and was expecting to be able to configure Prism syntax highlighting - eg. choose the theme, tweak the highlight style and so on. However I can't find anything in the docs about that - I can see the Prettier settings but nothing about Prism? That all seems hard-coded. This is an issue as the chosen theme is really hard to read and clashes badly with our own design.

Not sure if I'm just missing something, or if this is a feature request...

Please specify which version of Storybook and optionally any affected addons that you're running

Nope, it's indeed hardcoded. Want to PR?

BTW, @ndelangen and Co are working on overhaul UI changes, where this is addressed, but it will take some time to finish.

The UI overhaul will include theming for all syntax highlighting inside storybook.

Thanks for the advice. If I get time I'll take a look at a PR (won't be right away, just to be honest :)).
