Move to Histoire

[asvae]

Right now component demos play important role by ensuring high component quality. We use vue-book for that.

The problem with vue-book is that it's not well supported. Fortunately, modern alternative exists, which is pretty much the same functionally. It's called Histoire and it ships with native Vite support.

I reviewed it and I think it's a good fit for us.

This effort is useful for developers as well as @asvae, who'll have a talk on stories.

So here's the plan:

• Introduce Storybook #3293
• Deploy histoire to railway #3323, then @asvae should asyncronously settle things on his side:
  • Deprecate vue-book #3324
  • Remove current vue-book hosting #3325

• Play with Histoire for a couple of weeks, every developer could create a couple of demos and see if it works for them. Here's a couple of things we should probably pay attention to:
  • Is performance all right (Histoire uses iframes by default)?
  • Is it ok to debug?
  • and any other suspicion you may think of.

• If it doesn't work - we just rollback to vue-book. Dead end 👺.
• If it works we replace vue-book with Histoire.
  • .demo.vue files could be renamed to .story.vue.
  • Stories should be wrapped in <story> according to Histoire syntax. Stories should work without errors. Use script setup.
  • Remove vue-cli and anything vue-book related from ui package (files, scripts, deps).
  • Add information about histoire to contribution docs.
  • book staging should become histoire staging (modify docker file accordingly)

Next steps

• Experiment with story/variant docs
• Add figma link, similarly to storybook
• Visual and e2e tests
• Onboarding guide should have detailed readme on how to work with storybook on conceptual level
