support arm64

[johnB96]

When using the latest release (0.24.1), terraform init fails with the following message on arm64

╷
│ 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.
╵

hashicorp/template appears to be used referenced in examples and none of those examples use template_file so it should be trivial to remove that provider with something similar to sonatype@0be24ea

However, there are 3 upstream issues that need to be fixed first to fully support arm64

• GitHub provider not supported on arm64 macs (M1) cloudposse/terraform-github-repository-webhooks#34
• support arm64 cloudposse/terraform-aws-ecs-codepipeline#92
• support arm64 cloudposse/terraform-aws-ecs-web-app#187
