Update nw-ingress-configuring-application-domain.adoc

Wrong structure of command needs to be corrected
Here is the documentation link:
https://docs.redhat.com/en/documentation/openshift_container_platform/4.16/html/networking/networking-operators#nw-ingress-configuring-application-domain_configuring-ingress
Here is the current look:

Expose the route:

$ oc expose service hello-openshift
route.route.openshift.io/hello-openshift exposed
The above command is not structured properly.
We can use the above command as well, and it will execute perfectly.
But its structure is not as per our standard procedure.
Hence, it needs to be changed.
Here is the updated look:
Expose the route:

$ oc expose service hello-openshift
  route.route.openshift.io/hello-openshift exposed
