#1966 Adding Github Action for publishing multi-arch docker images on…

… DockerHub

Github action that triggers docker image build and publish action upon:
* merging into master using tag :master
* creating a new Prism Release with tags: latest, <major-version>, <full-version>

Additionally adding YARN_NETWORK_TIMEOUT to Dockerfile with default value set to Yarn's default.
This extra argument increases network timeout for arm64 Docker image builds since QEMU emulation tends to be slow.
