Fixed Docker build for ARM64 architecture on MacOS (M1/M2).

Issue #575

Description of changes:

Docker provides a build-time variable called BUILDARCH which automatically populates with the architecture (like amd64, arm64, etc.) when you use docker build or docker buildx build.

I utilized this variable to address the installation of some platform-specific tools. I trust this will be beneficial to the community.
