🐳 Refactor Dockerfile to decouple from Maven and enable CLI builds (#723)

* Refactor Dockerfile to decouple from Maven and enable CLI builds

- Dockerfile now uses a multi-stage build to download the aas4j-model (version 1.0.4) directly from Maven Central
- Removed dependency on Maven build output for external libraries
- Image can now be built using only `docker build`, without requiring Maven for dependency resolution
- Updated GitHub workflow to include Docker image build step

* Remove unused lines from docker file
