Refactor Dockerfile and buildspec.yml for Bun installation and command execution

- Remove direct Bun installation from the Dockerfile and install it as the nextjs user in a globally accessible location in buildspec.yml.
- Change the command to start the application from Bun to Node.js for improved compatibility and performance.
