data-ds-color-mode="auto" no longer works in storybook

[Barsnes]

This seems to only be an issue storybook.
This is me checking my color-scheme when in storybook:

This is on any other page:

It seems like this is caused by us setting color-scheme: light on :root

I suspect it has to do with Storybook using iframe for its docs/stories thats messing with getting the correct prefers-color-scheme? 🤔

This was fixed by adding a custom ident to iframes inside Storybook, color-scheme: auto;
