Description of your changes

The generator of Terraform module wrappers will create a fixed example and will not honor variables.

How can we test changes

repos:
  - repo: https://github.com/antonbabenko/pre-commit-terraform
    rev: v1.104.0
    hooks:
      - id: terraform_wrapper_module_for_each
        args:
          - --args=--module-dir=.
          - --args=--module-repo-org=terraform-company-modules
          - --args=--module-repo-provider=company
          - --args=--module-repo-shortname=product
          - --args=--verbose

This will generate a fixed example like this:

## Example: Manage multiple S3 buckets in one Terragrunt layer

`eu-west-1/s3-buckets/terragrunt.hcl`:

```hcl
terraform {
  source = "tfr:///terraform-aws-modules/s3-bucket/aws//wrappers"
  # Alternative source:
  # source = "git::[email protected]:terraform-aws-modules/terraform-aws-s3-bucket.git//wrappers?ref=master"
}
.
.

After this PR, the source examples should be like other examples

terraform {
  source = "tfr:///terraform-company-modules/product/company//wrappers/."
  # Alternative source:
  # source = "git::[email protected]:terraform-company-modules/terraform-company-product.git//wrappers/.?ref=master"
}

📝 Walkthrough

Walkthrough

Documentation example source references in the Terraform wrapper module were updated to use placeholder identifiers (MODULE_REPO_ORG, MODULE_REPO_SHORTNAME, MODULE_REPO_PROVIDER, WRAPPER_PATH) instead of concrete S3 bucket module names. No functional or runtime changes.

Changes

Cohort / File(s)	Summary
Documentation Template Update hooks/terraform_wrapper_module_for_each.sh	Replaced hardcoded module repository references with placeholder identifiers in example documentation for Terraform module source and alternative git source configurations

Title check	✅ Passed	The title references fixing an S3 example in the wrapper, which aligns with the PR's main objective of fixing the generator to use variables instead of hard-coded S3 module references.
