Simplify Docker build workflow and update dependencies

Refactored the GitHub Actions workflow to remove the build matrix and multi-arch manifest steps, consolidating the build into a single job targeting a specific build target. Updated the Dockerfile to add python-is-python3 and python3-dev to dependencies for improved Python compatibility.
