docs: remove unused playground

[Shinigami92]

closes #1256

• Removed the unused playground
  • if needed someday, we need to find a way to use it without initially load up >5MB
• Removed unused Badge component (not even sure what that was 🤷)
• Cleaned up the unused components folder, but we might need to bring that back if needed
