This script creates a directory `backend/package` which only contains the files required by the backend at runtime: - The contents of `dist` - `node_modules` minus `typescript` and `@typescript-eslint`. These packages are build-only and are larger than the remaining whole package. By using only `backend/package` in the Docker image, the backend content size in the image is decreased by 70% to 31M. This, along with the improved copying in the Dockerfile, reduces the backend image size by 44% to 200M. (Step `RUN chown -R 1000:1000 /backend ...` created a layer that effectively duplicated the backend.)
