AAP 60273: Add new HCP Terraform Credential Type

[jonquilwilliams]

https://issues.redhat.com/browse/AAP-60273

Affects two guides:

• Go to Chapter 22 in Preview Controller User Guide: https://jonquilwilliams.github.io/aap-builds/controller-user-guide-AAP-60273-2025-12-15.html

• Go to Chapter 1.2.1 in Preview GS with HashiCorp Guide: https://jonquilwilliams.github.io/aap-builds/terraform-aap-getting-started-AAP-60273-2025-12-15.html

On chapter 22, section 22.4.27

The wording here is slightly misleading. HCP Terraform is Terraform Cloud (TFC) not a separate platform.

The line
When using the hashicorp.terraform collection, you can use the HCP Terraform credential type for HCP Terraform or Terraform Enterprise (TFE/C).
could be rephrased as

When using the hashicorp.terraform collection, you can use the HCP Terraform credential type with Terraform Cloud (HCP Terraform) and Terraform Enterprise (TFE).
