terraform_data resource is misdetected as part of the deprecated external hashicorp/terraform provider

[amaxine]

Describe the bug

When using a terraform_data resource in a module and using terraform-docs to generate an updated README, the resource will be incorrectly linked to the registry docs, instead of Terraform documentation for this built-in resource type.

How can we reproduce it?

1. Create configuration using a terraform_data resource, e.g. copy and pasting from the documentation
2. Run terraform-docs against this configuration and verify that the generated README links to the incorrect documentation.

Environment information

• terraform-docs version v0.17.0 linux/amd64
• go version go1.21.6 linux/amd64
• NixOS 24.05
