bootstrap_extra_args (bottlerocket) ignored if use_custom_launch_template=false

[kr4sv]

When use_custom_launch_template is set to false on a managed node group, bootstrap_extra_args are no longer appended to the bottlerocket user_data.

bootstrap_extra_args not appended

managed-ondemand-nvidia = {
  use_custom_launch_template = false
  instance_types             = var.gpu_types
  ami_type                   = "BOTTLEROCKET_x86_64_NVIDIA"
  disk_size                  = var.mng_disk_size
  subnet_ids                 = [module.vpc.private_subnets[0]]
  bootstrap_extra_args       = <<-EOT
    [kubelet-device-plugin.nvidia]
    device-list-strategy = "envvar"
  EOT
  }

bootstrap_extra_args correctly appended

managed-ondemand-nvidia = {
  instance_types             = var.gpu_types
  ami_type                   = "BOTTLEROCKET_x86_64_NVIDIA"
  subnet_ids                 = [module.vpc.private_subnets[0]]
  bootstrap_extra_args       = <<-EOT
    [kubelet-device-plugin.nvidia]
    device-list-strategy = "envvar"
  EOT
  }

Not sure if this is by design (not documented though) or unintentional.

additional user data is only supported by EKS managed node groups via a custom launch template
