mon: do not show nvmeof in 'ceph versions' output

NVMeoF gateway version is independent of ceph version
so 'ceph version' shows wrong nvmeof version in output
(i.e. instead of gateway version, it shows Ceph version).
Hence, remove nvmeof in 'ceph versions' output.

To check for gateway version, use 'gw info' command.
