Add validation to Terraform configuration files used in acceptance tests

[gdavison]

Description

The Terraform configurations used in most acceptance tests are defined inline as Go strings, and we use GitHub workflows to validate the formatting and lint the Terraform code. As we move towards Terraform configurations in .tf files using ConfigDirectory, we no longer have these validation steps.
