Refactor Docker image tagging and manifest creation in GitHub Actions workflow

- Updated Docker image tags to use 'latest-amd64' and 'latest-arm64' for better clarity.
- Replaced traditional manifest creation commands with `docker buildx imagetools create` for improved efficiency.
- Streamlined the process for creating version-specific and major.minor tag manifests without pulling images.
