This action discovers the Terraform state directories that use the specified local modules.
A "state directory" is where you run `terraform plan` or `terraform apply`.
It usually contains the `terraform.tfstate` file.
For example, if you modify a Terraform local module, you can see which state directories are affected.
With this action, you can easily identify relationships in your Terraform configurations,
making it easier to manage changes and understand their impacts.
