The terraform-provider-template provider has been deprecated and is not supported on M1/Apple ARM CPU architecture: hashicorp/terraform-provider-template#85

Output from terraform init on an M1 Mac:

│ Error: Incompatible provider version
│ 
│ Provider registry.terraform.io/hashicorp/template v2.2.0 does not have a package available for your current

│ 
│ Provider releases are separate from Terraform CLI releases, so not all providers are available for all

Looking at the code, the deprecated provider appears to be used to provision the user_data for the CSR instances.

An alternative approach here would be to leverage the built-in templatefile function instead: https://www.terraform.io/language/functions/templatefile
