Fix the required version of terraform.

This was missed in #899 (and should be live now so it isn't version guarded).

So just to be 100% clear - the older version of terraform no longer works?

Correct. I tried using the older version and terraform apply gives an error (I don't recall which one) because we've started using syntax that was introduced in 0.12.

Also note that the terraform module linked from the guide pulls the agones configs from the master branch, so this has been broken since #889 was submitted.
