RHEL-08-020050 fails if loop list receives a single value

[SeanathanVT]

Describe the Issue
Logic for RHEL-08-020050 (specifically the “Update removal-action if exists” Task) fails if a single value is passed to the loop.

Expected Behavior
The task, and Role, should complete execution without issue.. Regardless of the number of items sent to the Task.

Actual Behavior
During execution, the loop was passed a single value (/etc/dconf/db/distro.d/20-authselect). A message is received stating the following:

Invalid data passed to ‘loop’, it requires a list, got this instead: /etc/dconf/db/distro.d/20-authselect. Hint: If you passed a list/dict of just one element, try adding wantlist=True to your lookup invocation or use q/query instead of lookup.

Control(s) Affected
RHEL-08-020050

Environment (please complete the following information):

• branch being used: Final STIG V1R11 (released 2024-03-19)
• Ansible Version: 2.15.3
• Host Python Version: 3.11.5
• Ansible Server Python Version: 3.11.5
• Additional Details: N/A

Additional Notes
N/A

Possible Solution
As suggested in the failed task, “try adding wantlist=True to your lookup invocation or use q/query instead of lookup”.

Posted a PR with a potential more straightforward fix. Shell returns both stdout and stdout_lines, so why not just use the one that is already a list?

@Phenix66 Thanks for handling that. I was swamped yesterday but was going to look more into it today -- you beat me to it!
