Include localhost and playbook examples

### Summary

From an internal JIRA ticket:

add example Ansible Playbooks where we talk about localhost and how cloud modules work. At the very least we should link back to the AWS guide and make it clear "where" to start.

NOTE: The AWS guide is associated with the amazon.aws collection. You could add a link to it from the readme. Also that guide may need to be updated if it needs to reflect this collection as well.

### Code of Conduct

- [X] I agree to follow the Ansible Code of Conduct

Start with the collection-level documentation and README, then review the linked AWS guide for the amazon.aws collection. Add localhost and cloud-module playbook examples, make the starting point clear, and ensure the README links to the relevant guide; update that guide only if its collection references are outdated.
