Linux demo updates bblasco podman

[benblasco]

Least effort update to this exercise so that:

• apache container populates index.html with appropriate contents
• Output of container execution is more readable

This addresses issue #36

Can you validate that this works along side the linux / patching job? I belive there have been some conflicts binding to ports in the past

[benblasco]

Will do.

@willtome Should not be an issue. Reporting job uses port 80, and the apache container is exposed on port 8080. Confirmed by testing on host and also checking code in collections/ansible_collections/demo/patching/roles/report_server/tasks/apache.yml and linux/podman.yml.
