[RFC]: Quality of life additions for Storybook integration

[virtuoushub]

• Allow for complete overriding of Storybook config, rather then merging [Bug?]: Can't customize Storybook! #6854
  • Better understand which Storybook defaults we are overridding - e.g. sbConfig.module.rules in webpackFinal, typescript.reactDocgen
• Allow for better independent deployment of Storybook artifacts GraphQL mocks do not work in built/deployed storybook #5534
• Support CSF 3.0 ( see: https://storybook.js.org/blog/component-story-format-3-0/ / fix(storybook): add args to auto generate docs #5979 (comment) )
• Add testing to CLI command (snapshot[s]?) to better capture merged webpack output ( see: Fix: dedupe addons when merging storybook main config #5592 )
• Support hot module update Storybook mocks don't hot module update #4717 - [ list of TODOs ]
• Add ability for stories around "stock" Redwood components (e.g. NotFoundPage, SignupPage, LoginPage, ...) to be generated ( [RFC]: Add Stories, Tests, and Metatags to the Scaffold Generators #6518 )
• provide better CLI mappings ( e.g. --no-open suggestion [ [Bug]: Storybook opens automatically though CLI doc implicitly suggests otherwise #6062 ] )
• Support merging webpackFinal / managerWebpack fix: handle Storybook webpackFinal merging separately #5957
  • Support async fields in Storybook configs ( see: https://github.com/survivejs/webpack-merge#limitations )
• Update generators to add args so docs addon works as expected ( see: Docs tab shows 'no code available' when using CSF format storybookjs/storybook#8104 (comment) )
  • fix(storybook): add args to auto generate docs #5979

Context:

From @dthyresson

Noticed that Storyboook does not render the NotFoundPage. I was customizing one and wanted to preview. ...

We may want to add one to the template. ...

This lead to a deep dive into the ways in which the Storybook integration can be improved.
