Move Docker build context artifacts to architecture specific locations

[robbavey]

This commit moves the Docker build context artifacts under architecture specific folders, and removes the TARGETARCH specifier introduced in #15980

This follows the guidelines for multi-architecture public Dockerfiles in https://github.com/docker-library/official-images?tab=readme-ov-file#multiple-architectures.

[robbavey]

To test, run rake artifacts:docker, and rake artifacts:dockerfiles, verify that the docker build contexts contain the correct artifacts for each architecture.

Docker images created can also be run and verifed

You probably have a phantom env2yaml file that was built a long time ago, so you are able to build the image.
Delete that file and rebuild everything should give env2yaml-amd64 and env2yaml-arm64 only
