Docker replacement request for PodMan

[ycMia]

Summary

Hi, I'd like to request the feature for Podman adaptation for this project.

Motivation

I Experienced a strict docker version check at this line :

docker_version=$(docker -v | grep -oP '\d+\.\d+\.\d+' | cut -d '.' -f 1)

It turns out that auto install will break in a result of

Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Cannot find Docker with a Version higher or equals 24.0.0
mailcow needs a newer Docker version to work properly...
Please update your Docker installation... exiting

I use Rocky Linux 9.1, on my VPS running. Thanks for any Idea or help.

Additional context

Using the last edition 37beed6 at Github.
