docker-compose not available in arm image. about docker-github-actions-runner

I've worked around this issue (and the scaling with docker-compose issue):

#72 (comment)

Wow good catch. I don't use docker-compose often so I guess I just had no idea!

$ k run --restart=Never -it --image=ubuntu:focal test
# ( apt-get update; apt-get install -y curl ) >/dev/null 2>&1
# DOCKER_COMPOSE_VERSION="1.27.4" curl -sL "https://github.com/docker/compose/releases/download/${DOCKER_COMPOSE_VERSION}/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# cat /usr/local/bin/docker-compose
Not Found

I made a quick PR to note this limitation and avoid installing it in ARM based builds in #100 if you'd like to review it @mrmachine
