Terrafile example

mod "sg", source: "terraform-aws-modules/security-group/aws", version: "3.10.0"

Resources: www.terraform.io/docs/registry/api.html

Latest version:

https://registry.terraform.io/v1/modules/terraform-aws-modules/sqs/aws/2.1.0/download

The latest version returns an 302 and contains a location header that is followed and then downloaded the same way the specific version is downloaded.

Specific version:

https://registry.terraform.io/v1/modules/terraform-aws-modules/sqs/aws/download

The specific version returns an 204 and then we grab the download url info form the x-terraform-get header.
