Var name inconsistent between `defaults/main.yml` and actual task usage

Describe the Issue 5.2.4 uses some vars, like: allowusers, allowgroups, denyusers, denygroups, while in defaults/main.yml these vars were declared with underscores:

allow_users, allow_groups, deny_users, deny_groups

Expected Behavior Vars name should be the same.

Actual Behavior Vars name is different, thus tasks are skipped, since the condition will never be met(value for these vars will be empty):

TASK [/mnt/d/code-siemens/iss_pss_gov/infosec-pss-gov/security-crafter-baseline-automations/Ansible-Lockdown/rhel9-cis : 5.2.4 | PATCH | Ensure SSH access is limited | Add line to sshd_config for allowusers] ***
skipping: [192.168.2.133] => {"changed": false, "skip_reason": "Conditional result was False"}
