Update source and version for aws provider

[daz10000]

Thanks- this was hugely helpful. I did run into some confusing errors (not a terraform expert), which were finally resolved by updating the required providers section to this. Happy to send a PR if you're open to updating,

$ cat terraform.tf
terraform {
  required_version = "~> 1.2"

  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "5.8.0"
    }
  }
}

provider "aws" {
  access_key = var.aws_access_key
  secret_key = var.aws_secret_key
  region     = var.region
}

It was previously throwing an error during init
