Fix missing package json when spinning up the game_controller

[wantsui]

What does this PR do?

Fix the rolldice-game app.

Motivation

When I try to spin up the app in apps/rolldice-game/, the game_controller container fails to spin up with this error:

Error: Cannot find module 'express'
Require stack:

  code: 'MODULE_NOT_FOUND',
  requireStack: [ '/game_controller/game_controller/controller.js' ]
}

This has to do with how the Dockerfile currently copies files over.

The folder with the package.json is /game_controller/game_controller , not /game_controller.

After this fix, the following containers images should spin up:

• rolldice-game-game_controller
• rolldice-game-rolling
• rolldice-game-scoring
• otel/opentelemetry-collector-contrib
