Add arm64 docker image

[ysohma]

1. Content and background

Distributed docker image is not compatible with ARM environments such as Apple Silicon Mac. Although Docker offers emulation for x86/amd64 environments, onnx2tf within this emulation mode results in an error, as shown below:

$ root@39d07181ce27:/# onnx2tf -h
> Illegal instruction

This issue is suspected to be caused by the dependency of PyPI TensorFlow on x86-specific instruction sets.

To address this, I've augmented the release process with GitHub Actions to include building and pushing Docker images for Arm64 architecture. This make it possible to execute onnx2tf with docker on Arm64 hosts.

2. Summary of corrections

• Update Dockerfile
  • Extra dependencies (pkg-config and libhdf5-dev) are required to install h5py for arm64 docker build.
• Add Arm64 build and push in GitHub Actions
  • Referenced the following URL for guidance: https://docs.docker.com/build/ci/github-actions/multi-platform/

New workflow is tested on my repo, built and push successfully. Also I checked some test command can work on it. My test workflow: https://github.com/ysohma/onnx2tf/actions/runs/9138403803

Amazing!

Release workflow run successfully. However amd64 image is missing in the registory. It seems to be overwritten by second(arm64) push.

I've found the solution for this. https://docs.docker.com/build/ci/github-actions/multi-platform/#distribute-build-across-multiple-runners

I will submit new PR to fix it in few days.
