data "template_file" not supported on M1 chips

When running terraform init using v4 of this module, I get

╷
│ Error: Incompatible provider version
│ 
│ Provider registry.terraform.io/hashicorp/template v2.2.0 does not have a package available for your current platform, darwin_arm64.
│ 
│ Provider releases are separate from Terraform CLI releases, so not all providers are available for all platforms. Other versions of this
│ provider may have different platforms supported.
╵

https://github.com/hashicorp/terraform-provider-template/issues/85 suggests this is because template_file has been replaced with templatefile()
