OpenStack: fix IPv6 docs

Browse Source 
Given we are using a provider network in the example, we
should recommend adding the network in the router as external gateway
instead.

## Creating Dual-Stack Networks for the cluster
You must create one network and add one IPv4 subnet and another IPv6 subnet with either slaac, stateless or stateful modes. Also,
you must add the IPv6 subnet to a router. Here is an example:
You must create one network and add one IPv4 subnet and another IPv6 subnet with either slaac, stateless or stateful modes. Here is an example:
```sh
$ openstack network create --project <project-name> --share --external --provider-physical-network <physical-network> --provider-network-type flat dualstack
$ openstack subnet create --project <project-name> subnet-v4 --subnet-range 192.168.25.0/24 --dhcp --dns-nameserver <nameserver> --network dualstack
$ openstack subnet create --project <project-name> subnet-v6 --subnet-range fd2e:6f44:5dd8:c956::/64 --dhcp --network dualstack --ip-version 6 --ipv6-ra-mode slaac --ipv6-address-mode slaac
$ openstack router add subnet <router-id> subnet-v6
```
Note the example above creates a provider network, but a creation of a tenant network is also supported, which must be connected to a router for external connectivity.
Given the above example uses a provider network, this network can be added to the router external gateway to enable external connectivity and router advertisements with the following command:
```sh
$ openstack router set --external-gateway dualstack <router-id>
```
