Support ansible-test integration tests for arm64

[AndrewJDawes]

SUMMARY

The ansible-test integration tests are currently failing when run with the --docker environment on a Debian-based OS running on arm64 architecture.

This is because the step that adds the Docker repository to apt is currently hardcoded to add only the amd64 repository.

So, in later steps when we try to use apt to find and install the docker-ce-cli package, this step fails on arm64 hosts with this error message: No package matching 'docker-ce-cli' is available.

This PR updates the test setup steps for Debian-based hosts to detect the host's architecture and add a repository that supports this architecture.
