Remove unused dependencies

[pguinard-public-com]

Describe the Bug

required_providers { local ... } is not required as locals are built into terraform. The local provider provides the following:

• resource.local_file
• resource.local_sensitive_file
• data.local_file
• data.local_sensitive_file

Expected Behavior

Not install a provider that is not required in order to speed up the terraform init process.

Steps to Reproduce

Sample terraform code

module "container_definition" {
  source  = "cloudposse/ecs-container-definition/aws"
  version = "0.58.1"

  container_name  = "app"
  container_image = "image:latest"
}

$ terraform providers

Providers required by configuration:
.
├── provider[registry.terraform.io/hashicorp/aws]
├── module.container_definition
│   └── provider[registry.terraform.io/hashicorp/local] >= 1.2.0
