CLI command to detect what K8s distro is being used

[RothAndrew]

This might be a good new issue to expose the distro detect stuff on the CLI. It would be really clean for a zarf tools what-distro or something command to tell the user about their kubecontext + detected distro.

@RothAndrew @jeff-mccoy Help me understand why this is important in the context of Zarf. Also, we're talking K8s distro not OS distro correct?

K8s distro, we do it internally, might be helpful to just expose it.
