align output keys with terraform backend keys.

small improvement but would make copy paste possible.

This can solved easily with having an output in the code like this which creates the backend.tf block.

output "backend_output" {
  value = {
    bucket         = module.terraform_remote_state.state_bucket.bucket
    key            = "ADDYOURKEYPATHHERE"
    dynamodb_table = module.terraform_remote_state.dynamodb_table.name
    region         = data.aws_region.current.name
    profile        = var.profile
  }
}

in addition, I'd recommend to create a local_file that contains the output.
I'm keeping all my backends to a dedicated folder.
A side note: I'm using an empty variable (var.env) and terraform apply prompt the user for input. this var is also the file name in my case.
