TKG checks Docker version, but not Podman

[LongyuZhang]

Currently TKG has the function of checking Docker version, but for machines with Podman, it will show docker : not on docker We can add a similar function to check Podman too.

We should check both docker --version and podman --version. Please update the current CHECK_DOCKER_CMD and add check for podman.
