Support Multi Arch Images

[Kenec]

With the changes introduced in #777, only AMD 64 is supported. It would be nice to support other types of architectures.

Example of error message when attempting to use the current image in a custom github runner running on ARM 64

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

Hi @Kenec, thanks for writing in! For context, these images were intended for use in the GitHub Actions ubuntu-latest runner. This isn't on our roadmap at the moment but we'll post any updates here as we have them.

As a workaround in the meantime, you're welcome to clone this repo and build the image yourself (here's the Dockerfile we use to build the image for reference) or you can install rdme via the npm registry. Hope that's helpful!
