Remove call to deprecated TF provider

[jgadling]

The hashicorp/template provider is deprecated now and prevents swipe from being set up while running terraform from ARM machines.

% terraform init

.....
╷
│ 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.
