Fix iteration documentation

[luisffc]

• Loop requires the until
• Even if I add the until, it fails
• Also, the step type step was replaced

  step "pipeline" "create_iam_role" {
    pipeline = aws.pipeline.create_iam_role
    args = {
      cred      = param.aws_cred
      role_name = param.role_name
      assume_role_policy_document = param.assume_role_policy_document
    }

    loop {
      if = loop.index < param.amount
    }
  }

gives me

Error: Failed to decode mod:
Missing required argument: The argument "until" is required, but no definition was found.
(/Users/luis/steampipe/pipeling-scale-testing/scripts/aws/create_iam_roles.fp:57,10-10)
Unsupported argument: An argument named "if" is not expected here.
(/Users/luis/steampipe/pipeling-scale-testing/scripts/aws/create_iam_roles.fp:58,7-9)

and

  step "pipeline" "create_iam_role" {
    pipeline = aws.pipeline.create_iam_role
    args = {
      cred      = param.aws_cred
      role_name = param.role_name
      assume_role_policy_document = param.assume_role_policy_document
    }

    loop {
      until = true
      if = loop.index < param.amount
    }
  }

gives me

Error: Failed to decode mod:
Unsupported argument: An argument named "if" is not expected here.
(/Users/luis/steampipe/pipeling-scale-testing/scripts/aws/create_iam_roles.fp:59,7-9)

this works fine

loop {
      until = loop.index < param.amount
    }

Looks like documentation has been updated to be correct, closing.
