what

Support user_data_replace_on_change:

[user_data_replace_on_change](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/instance#user_data_replace_on_change) - (Optional) When used in combination with user_data or user_data_base64 will trigger a destroy and recreate when set to true. Defaults to false if not set.

Force a rebuild if user data has changed.

Thanks @bwmetcalf would you mind generating the readme again? If it outputs >= 0.13 again for min tf version, please delete any lock files you have and try again.
