Subject: [PATCH 1/2] Refactor Dockerfile.n8n for improved npm package
 installation and environment configuration

- Updated the npm install command to install packages directly into n8n's app directory, enhancing organization and ownership management.
- Replaced N8N_EXTERNAL_MODULES_ALLOWLIST with NODE_FUNCTION_ALLOW_EXTERNAL for better clarity in external module configuration.

These changes streamline the Docker build process and improve the overall setup for the n8n service.
