Function CacheTFProviders

testutil/terraform_cache.go:179–185

CacheTFProviders caches providers locally and generates a Terraform CLI config to use *only* that cache. This setup prevents network access for providers during `terraform init`, improving reliability in subsequent test runs. Returns the path to the generated CLI config file.

// Returns the path to the generated CLI config file.
