Run Pi-hole as a container with Podman

There is arguably no better way to protect devices on your local network from unwanted content than [Pi-hole](https://pi-hole.net/). Add a machine running Pi-hole to your network, and it will quietly scrub all incoming traffic from pesky stuff like ads and trackers in the background. As the name suggests, Pi-hole was initially designed to run on a Raspberry Pi. But if you already have a Linux server on your network, you can deploy a Pi-hole container on it instead.
