Improve storybook docs page

[hsablonniere]

We setup Storybook's docs page but there are still details that could be improved:

Remove notes and only use docs page

To do so, we need to improve docs page because right now:

• :cry: Props table does not merge attrs/props (done with SB6)
• :cry: Props table does not list methods
• :cry: Props table does not display event types

Improve docs page

• Code blocs in description are not syntax highlighted. We used them to describe types maybe we can find another way.
• Compile static storybook with --docs to simplify tree and usage.
  • Beware, this means not having addons/actions at all :thinking:
• Add details about default CSS display
• Link to source
• Improve format/indents for stories' "show code"
• Use attributes instead of properties in stories' "show code"
• Provide tabbed interface for stories' "show code" with: "HTML", "Vue.js", "Angular", "JSX/(P)react", "Svelte"...
• Display a list of translation keys used by a component
• Display a list of the deps used by a component
  • images
  • internal deps
  • 3rd party deps
• Display stats about sizes
  • images
  • internal deps
  • 3rd party deps
  • CSS

NOTE: While we wait for something more reliable and automatic, we have manual details for:

• default CSS display
• ~link to source~ DONE
• ~list of images~ DONE
