Refactor GitHub Actions workflow for multi-architecture Docker builds

- Streamlined the Docker build process by organizing steps and removing redundant configurations.
- Enhanced artifact preparation by ensuring executable permissions for architecture-specific binaries.
- Maintained support for multi-architecture builds (amd64 and arm64) while improving clarity and efficiency in the workflow.

These changes optimize the CI/CD pipeline, facilitating seamless builds across different architectures.
