Update docs for using venv (#8842)
Due many patterns of Linux distributions, it is difficult to install
ansible dependencies as system-wide stably.
Apart of Kubespray doc[1] recommends to use venv to avoid such issue,
and this applies venv usage to the other parts of the doc.

fix typo / error regarding etcd and k8s_cluster groups (#8580)
As far as I can tell this is simply a typo that has existed from the beginning. Having it this way around (`etcd` group as a child and thus subset of `k8s_cluster`) mirrors what is written in the preceeding sentence.
