Remove Puzzle app from the Playground website (#1588)

## Motivation for the change, related issues

The Puzzle app was used during WCEU 2024 to scan puzzle pieces.
Now after the event is over, we need to remove the app from
Playground.WordPress.net.

If we want to bring it back for a future event, we can revert this PR.

## Implementation details

The PR removes the redirect necessary for app routing to work and the
build plugin which adds the Puzzle app to the Website build.

## Testing Instructions (or ideally a Blueprint)

- ensure all tests pass
- `npm run build:website && php -S localhost:9999 -t
dist/packages/playground/wasm-wordpress-net`
- Open http://localhost:9999/puzzle/ and ensure you don't see the puzzle
app
