fix: use TARGETARCH for multi-platform Docker builds

Browse source 
Use Docker's TARGETARCH variable to download the correct architecture
binaries for Go and Hugo during multi-platform builds. This fixes the
build failure for linux/arm64 where amd64 binaries were being downloaded.

- Add ARG TARGETARCH to capture target architecture
- Replace hardcoded linux-amd64 with linux-${TARGETARCH}
- Applies to both Go and Hugo downloads
- Backwards compatible with local single-platform builds
