publish arm64 images to Docker hub

[SvenDowideit]

Brief summary

so I found #3015, which seems to imply that the arm64 image is buildable, but when I goto https://hub.docker.com/r/grafana/k6/tags there's only a linux/amd64 image.

k6 version

any

OS

OSX, Docker Desktop, Ubuntu,

Docker version and image (if applicable)

No response

Steps to reproduce the problem

go to https://hub.docker.com/r/grafana/k6/tags - at this point 0.46.0 is the current release, and unlike (for eg https://hub.docker.com/r/grafana/grafana/tags ), the k6 image is not multi-arch

Expected behaviour

the desired nirvana would be that all the architectures work - in my case, it'd be nice for my arm64 systems to be happy without needing the cross-arch support :)

Actual behaviour

multi-arch images, or a nice sentence of why it doesn't make sense to do it atm, and who could help make it happen / change that

Hey @SvenDowideit, a new image supporting linux/arm64 is now available for the grafana/k6 master tag. https://hub.docker.com/layers/grafana/k6/master/images/sha256-ab124b905466c8b75699424e1a76eba8c46d0af0689dff3fa04764d0f3d1368e

Can you give it a try and let we know if it works for you?

We will start pushing the linux/arm64 images for stable versions from the next release of k6.
