Switch test yaml to docker driver

The podman driver is flakeky locally and consistently failing in github
actions now. Switching to docker fix the issues in github.

Developers need to install docker to run drenv test locally. I tried to
use the podman-docker pacakge but it does not emulate docker good
enough for minikube.
