Remove unnecessary Docker container - use simple approach like composefs

- Remove Docker-in-Docker complexity that was causing build script issues
- Use direct approach on Ubuntu runner with Debian repositories
- Follow the same pattern as the working composefs CI
- Much simpler and more reliable - no container networking issues
- Just add Debian repos to Ubuntu runner and build directly
