stories.json missing from Storybook 8 (composition)

[marksy]

Summary

I'm using composition to show two instances of Storybook.

I'm hosting them on my private GitHub Pages, however it seems to be requesting stories.json and when I check my local build folder it's not in there.

I read that the previous version of Storybook had the ability to buildStoriesJson:

features: {
        buildStoriesJson: true,
    },

But I think this isn't supported in v8.

Oh! unless it's been renamed to index.json 🤔

Storybook seems to still be requesting stories.json though
