Reference to unused "connection" keyword in Ch.2

[qmacro]

In the first warning note in the "Hello, Ansible!" section you refer to a connection keyword that hasn't been referenced so far.

Thanks; that was from an initial version of the playbook which defined the connection: local inside the playbook instead of the inventory, but as you say it doesn't make sense there with the current version of the playbook!

I'll have this fixed in the next book release.
