feat: implement multi-architecture Docker build workflow
- Added separate jobs for building and pushing AMD64 and ARM64 Docker images. - Configured conditional execution for ARM64 builds to only run on the main branch. - Enhanced the Docker build process with digest export and artifact upload for both architectures. - Created a job to generate a multi-architecture manifest after successful builds. - Updated tags and labels for better image management.
