github: Fix latest linter errors

[Haroon-Khel]

• commit message has one of the standard prefixes
• faq.md updated if appropriate
• other documentation is changed or added (if applicable)
• playbook changes run through VPC or QPC (if you have access)
• VPC/QPC not applicable for this PR
• for inventory.yml changes, bastillion/nagios/jenkins updated accordingly

Using warn: False/warn=False is deprecated, which is causing linter errors
FAILED! => {"changed": false, "msg": "Unsupported parameters for (ansible.legacy.command) module: warn. Supported parameters include: _raw_params, _uses_shell, argv, chdir, creates, executable, removes, stdin, stdin_add_newline, strip_empty_ends."}

For the aix yum task, the yum role is deprecated. We install dnf on 7.2+ so I am comfortable removing the warn option there. For the ccache role, running the task without the warn makes no difference to the output, so i've removed it for that task
