Doc: Fix tilt up issue in feature discovering in developer guide

Browse source 
The issue is due to the k3d/kind cluster created by ctlptl will run
inside containers(it will serve as the virtual hosts).

Host folders which will be scaned by the nfd feature discovery should
be mounted into the container ( the virtual host). otherwise the nfd-worker
container which run inside the virtual host will just see the default base
image rootfs /boot, /lib folders, which are usually empty, leads to the
discovey failure.

To start up your Tilt development environment, run - Create a Kubernetes cluster. Please note that docker containers will be
served as controller node and worker nodes, and NFD-worker will run as a
DaemonSet in nested container. Therefore, to make sure the NFD-worker can
discover the host features, the host folders "/boot" and "/lib" should be
mounted into worker node docker containers when creating the Kubernetes
cluster.
1. Start up node feature discovery development environment
To start up your Tilt development environment, run at the root of your
