Reformat for Terraform Registry

Hi team,

renamed the path of the source to the module registry instead of the GitHub repo

removed variables because all variable information is sourced from the variable and output files.

removed figure diagram because the Terraform Registry cannot render the image

If you can merge this into master and then add another release/tag so that the module registry will update. After that we'll be able to verify this module.

Thanks
Chris
