ci: add support for VM_DRIVER=podman to scripts/minikube.sh

When running on AWE EC2 virtual-machines, we'll use Podman instead of
installing a VM. The "none" driver might work as well, but it requires
additional dependencies to be installed, which may change over time with
new minikube or Kubernetes releases. Hopefully the Podman driver is less
affected with changes in dependencies.

Depends-on: #3419
Closes: #3415
