Update docs to reflect change, rename terraform-iac/ to terraform/

Docs needed to be updated either way.

I know we've done some bikeshedding on the directory name before. I
didn't previously care whether it was called terraform/, iac/,
terraform-iac/ or anything else. Nowadays, I have a tiny reason to
prefer the name terraform/: it plays nicely with automatic folder
icons. The other options don't.
