feat(docs): Add note to address having the same name as new Terraform…

… stacks feature

Since CDKTF has a primitive called stacks and we also have an upcoming (now announced) feature that is also called "stacks" or "Terraform stacks" - I wrote a sentence with a link to point out the differences.

 # Stacks
 
+_Note: Stacks in CDKTF are not the same as [Terraform stacks](https://www.hashicorp.com/blog/terraform-stacks-explained), which are a configuration layer that eliminates the need to manually manage cross-configuration dependencies between Terraform modules.
+
 A stack represents a collection of infrastructure that CDK for Terraform (CDKTF) synthesizes as a dedicated Terraform configuration. Stacks allow you to separate the state management for multiple environments within an application.
