fix: Correct conditional checks for PSA config existence and Ansible managed comments

[ismoilovdevml]

What type of PR is this?

• bug

What this PR does / why we need it:

This PR addresses two related issues in the add-pod-security-admission-config.yml task of the RKE2 server role:

1. Fixing Conditional Check for PSA Config Existence: The previous conditional used is false, which caused an Ansible error. The condition is now correctly evaluated with not and | bool to check the PSA config file's existence.
2. Fixing Conditional Check for Ansible Managed Comments: The check for Ansible managed comments also used is false incorrectly. This has been corrected using not and | bool to ensure that the file is only removed if it contains Ansible managed comments.

Which issue(s) this PR fixes:

there is no such issue

Special notes for your reviewer:

Please review the changes to ensure that:

• The PSA config file is properly checked for existence before removal.
• The check for Ansible managed comments functions as expected.

Testing

Tested locally by running the playbook with and without the PSA config file. Verified that the file is only removed when it exists and contains Ansible managed comments.

Release Notes

Fix conditional checks in RKE2 server role for PSA config file existence and Ansible managed comments to prevent errors during playbook execution.
