feat(storybook): remove root config files

[mandarini]

Remove the root config directory and files, since they do not really offer much.

This SHOULD go into a RELEASE

• Automatic migration is not possible for all use cases
• Write migrator that ONLY adds @storybook/addon-essentials to all project-level storybook instances and removes it from root storybook .storybook/main.js file
• GUIDE explaining how this is not a breaking change - old config still works - it's just new generator does not generate root config
• Explain why users should move to project-based config and abandon root config, but they can keep the root if they want to
• Explain how they can create a root if they want to
• If root config is empty, migrator removes it and removes its imports from everywhere
• If root config is not empty (after removing @storybook/addon-essentials, then leave it as it is)

TODO:

• Remove rootMain.webpack config stuff too
• Write guide and explanation
• Create migration object into the migration array

TESTING:

Tested it locally and it works. I have a workspace with angular, react, nextjs, web-component apps and libs, with storybook, migrated to new setup and all works as before.
