Why not enable hack_terraform_docs when terraform-docs is >= v0.8.0. This will allows us to maintain temporary 2 versions of terraform-docs.

@antonbabenko @konstantin-recurly Any thoughts ?

I agree. It makes perfect sense to stay compatible for as long as possible.

I have updated the logic and added the check for terraform-docs version.
It is checking if terraform-docs version is >= v0.8.0 also added a check if terraform-docs is installed.
