Subject: [PATCH] Don't use deprected template provider

The template provider was archived and should be replaced by other
alternatives:

https://github.com/hashicorp/terraform-provider-template/issues/85

I used a here-document with variable interpolation.

The main motivation is that the provider is not available for all
platforms (especially arm64 which is being used by modern macs)
