Add support for Terraform 0.12 using terraform-docs12 Helper (#4)

* drop python2 support

* Currently terraform-docs v0.6.0 does not support HCL2 (terraform 0.12) code.
Wrappers were built pre-processing those HCL2 files so that terraform-docs can be used.
A python3 script is available and needed as a prereq to this hook.

* include terraform-docs12 dependancy
