Incorrect configuration in scripts examples

There is misconfiguration in **orchestration/scripts/hosts.ini**
Docker is unavailable as an _ansible_connection_ method, therefore nothing works.
You have to copy&paste hosts.ini from the upper level directory and Bob's your uncle!

Take this into consideration, please!

P.S. I meant [this](https://github.com/geerlingguy/ansible-for-devops/blob/master/orchestration/scripts/hosts.ini) configuration file

Compare orchestration/scripts/hosts.ini with the upper-level hosts.ini referenced in the issue, focusing on the ansible_connection setting. Update the scripts example to use the working configuration, then verify that the orchestration example can run with Docker available.
