Get pihole listening on the local IPv4 and IPv6 addresses.

I'm not sure if the defaultNetwork subnet changes are necessary, I was trying
lots of stuff. There are some whitespace changes as well, don't get
distracted by them.

Most critically the --network=bridge is and the dns_enabled=false avoid
starting the aardvark-dns thing that podman does for internal dns on
port 53 and make it so the container gets the IPv6 address for listening
to incoming requests.
