Use Storybook instead of demo components in /playground

[rifandani]

What problem is this solving

• build, view, test, debug, and document UI components in isolation
• develop hard-to-reach states and edge cases without needing to run the whole app
• track components history and versions
• we can publish the documented UI components
• hundreds of addons that helps build UI faster, document component libraries, and integrate with other tools

Proposed solution

• delete all demo components in /playground
• use storybook
• setup storybook CI
