This PR adds the `publish-docker-image-multiplatform` CI job step that pushes a multi-platform docker image when a new tag is created. #1211 Unfortunately, this is not as simple as pushing two images targeting different platforms to the same tag. There are a couple of ways to create a multi-platform image: - Using `docker buildx` to build images for all platforms. To do this images targeting non-native platforms would need to be built using QEMU (slower), a remote machine or cross-compilation. - Building and publishing platform-specific images `emscripten/emsdk-x64`, `emscripten/emsdk-arm64` and then creating a manifest that links to these images. This is the simpler solution to implement, and is what this PR does. Tested with CircleCI on my fork. See the pushed images at [radiantly/emsdk · DockerHub](https://hub.docker.com/r/radiantly/emsdk/tags)
