Support multi-architecture Docker image

[denisa]

Apple is transitioning its computer to a arm64 architecture

While amd64 can be executed, sometime, this is slower.

Could the project build an image that supports both amd64 and arm64?.

What would you think of arm64 images, like with a -arm64 suffix? That should be pretty trivial to add :)

Do you mean https://goreleaser.com/cookbooks/multi-platform-docker-images/?h=multi ?

In the ideal end-state, there is a single image and docker dynamically downloads what’s appropriate at execution time

I tried adding support for separate arm64 images here https://github.com/yannh/kubeconform/actions/runs/4971934488/jobs/8896808560 but hit some issues and reverted for now. This is also pretty difficult for me to test - since I do not own a mac.
I don't have much more time today, but would happily merge PRs to add support here. Also happy to add support for multi-arch images.

See #204
