arm64 support in docker image

I'm texting CodeX Docs in Docker, and was unable to get it up and running on my arm based server due to missing architecture support. I have successfully spun it up on a x86 host, however arm support would simplify the setup.

Not sure of the effort to include an arm build in the docker registry for the project, so if this is an unreasonable request let me know.

该 issue 指向 Docker 镜像及其 registry 发布，但没有指定任何文件或测试。首先定位镜像构建和发布配置，然后检查当前如何定义架构支持。发布 arm64 镜像，并且应用程序能够在基于 arm 的服务器上成功启动，即视为完成。
