ansible_connection unclear in README

[mwk24]

The readme suggests the line:

matrix.YOUR.DOMAIN ansible_host=YOUR_SERVERS_IP ansible_connection=local ansible_ssh_user=root ansible_connection=community.docker.nsenter

This seems off to me:

• There are 2 values for ansible_connection: local and community.docker.nsenter. this can't be right
• nsenter is designed to allow ansible in a container to act as the host (afaik), so I don't see the utility of this when using ssh to the server (as the README is describing), when surely the commands are run as root via ssh?

nsenter is useful when ansible is run in a container on the matrix host itself, afaik. (how this is different to --privileged would be useful to know also)

Also - not sure why docker installation is disabled for the target matrix host.
