misleading doc example for dns_zone_info

[znalo]

in source at:

https://opendev.org/openstack/ansible-collections-openstack/src/branch/master/plugins/modules/dns_zone_info.py

and in the current published ansible module documentation at:

https://docs.ansible.com/ansible/latest/collections/openstack/cloud/dns_zone_info_module.html#ansible-collections-openstack-cloud-dns-zone-info-module

the examples for the openstack.cloud.dns_zone_info use
"openstack.cloud.dns_zones:"
Which does not appear to work for me.
I think they should use
"openstack.cloud.dns_zone_info:"
Which appears to work for me.
