fix(barbuk): Handle podman as docker_host in docker segment

[BarbUk]

Description

The docker segment will now detect if a podman socket is present and display the information.

Motivation and Context

Migrated to podman, wanted to have the correct information displayed.
Before that, podman was not considered at all.

How Has This Been Tested?

On a directory that contain a dockerfile or dockercompose, this will now display a podman logo + test.
