replace name with address in format argument

Minor bug fix in this doc.

Can you explain this change? I have just gone through the tutorial and don't remember that stuff broke at this point.

One related thing did bite me though: First we use the variable KUBERNETES_PUBLIC_ADDRESS to hold the name, for the external network load balancer resources. Then, in verification, we reuse the variable to hold the address. At first, I did not update the variable (so it still held the name), and then the curl command failed.

Thanks.

It seems to work both ways (with reserved address name and IP).
Feel free to reject #294 if you decide that using actual IP is the right way.

Let's leave it alone for now because it works.
