PR support for RHEL 9 (Plow) + ansible-core 2.13.3

[salanisor]

Read issue #296 and thought I'd share the recent work I had to do to get this working on RHEL 9.

Please note that I installed ansible provided via EPEL which in turn pulled in ansible-core and libraries from their respective RHEL repositories and that is what I used to execute these changes.

Note: I faced an issue attempting to loop through the critical services fact, so I ended up moving it into a list and it just worked without issue.
