RHEL 8+ yum-plugin-ps detection fails

**Describe the bug**
RHEL 8+ based VMs fail to run 'yum ps' because the yum-plugin-ps detection is broken.
The failure is on this line the command output is looking for 'yum-plugin-security' however it should look for 'yum-plugin-ps' as that package is being tried to install
