TrueNAS Scale documentation improvement
### Describe The Bug

I was following along with the guide here: https://github.com/homebridge/docker-homebridge/wiki/Homebridge-on-TrueNAS-Scale

I have a few suggestions to make this guide better.
First of all the guide offers a hacky way to get things to work by creating a 2nd NIC, then adding a startup script to remove the default one, including having to use enable `CAP_NET_ADMIN`.

The biggest problem with this approach is that homebridge is not able to communicate with other services running in the kubernetes cluster. In my particular case I use zigbee2mqtt, and I have mosquitto running in the cluster, but homebridge is unable to access it.

Instead, I recommend to just leave both interfaces active, make sure to enable Kubernetes DNS instead of ignoring it, and simply telling homebridge to only advertise on `net1` and not `eth0`. You also need to pick an mDNS Advertiser other than bonjour HAP, such as avahi which can actually support specifying the interface to advertise on instead of just automatically picking the first one it sees.

This way homebridge is properly advertised on the secondary NIC, but you also get the first NIC to access k8s, and it is setup with your default gw etc.

This is how I have it setup and its working very well.
