MacOS - podman container stats is failing with missing `cgroups v2`

Context

➜ podman machine list
NAME                     VM TYPE     CREATED      LAST UP

➜ podman --version
podman version 3.3.1

podman container stats ID ends with Error: stats is not supported in rootless mode without cgroups v2

But

podman machine ssh podman container stats

Works without an issue, command is missing a remote check.

I think the check for unified and rootless needs to be moved away from client to backend.

I take this one.
