Refs #15963 - Fix documentation typos

[itsbill]

Hi,

This is one of a series of patches to address typos in katello-installer --help #15963

This diff addresses the --certs-deploy, --certs-regenerate, and --certs-regenerate-ca parameters' descriptions, changing them from:

   --certs-deploy                Deploy the certs on the configured system. False means
                                 we want apply it on a different system (current: true)
...
   --certs-regenerate            Force regeneration of the certificates (excluding
                                 ca certificates) (current: false)
...
   --certs-regenerate-ca         Force regeneration of the ca certificate (current: false)

To:

   --certs-deploy                Deploy the certs on the configured system. False means
                                 we want to apply it to a different system (current: true)
...
   --certs-regenerate            Force regeneration of the certificates (excluding
                                 CA certificates) (current: false)
...
   --certs-regenerate-ca         Force regeneration of the CA certificate (current: false)

Thanks in advance!
