feat: Ignore NG's Launch Template Version Change

[Efrat19]

PR o'clock

As a heavy user of this module, every time I run the terraform apply I get frustrated by the fact I all of my managed nodegroups are updated, regardless of the change I made to the TF stack.
The update is to the LT version, from "2" to "$Latest", even though in my configuration the version is already set to "latest":

My configuration look like this:

module "eks" {
  source          = "terraform-aws-modules/eks/aws"
  .....
  workers_group_defaults = {
    .....
    create_launch_template   = true
    launch_template_version = "$Latest"
  }
}

But when I run terraform plan, I see that terraform is aiming to change the version:

Description

I added the LT version to the ignore list in hope this may help other people using this module

#1447 looks like a much better fix, since it handles the case where the specified launch template version is not "$Latest".

I agree, thanks!
