Feature Request - AWS CloudFormation Git sync

### Name of the resource

Other

### Resource name

CloudFormation Git sync

### Description

While using the new feature of CloudFormation Git sync it will update the stack when there is a push/merge in the code and then it creates the ChangSet and Executes the changes automatically.


**From the document:**
When you commit changes to the template or the deployment file, CloudFormation automatically updates the stack[1]

**Feature Request to the team:**
Instead of automatically Updating the stack (executing ChangeSet) can we have a new functionality where user can execute the ChangeSet so that they can check if the update on the CloudFormation template will trigger any replacement update or modify when using GitSync.

This can be very helpful for stacks which are in production environment

The issue provides no repository files or tests. Start with the linked AWS CloudFormation Git sync documentation and the described automatic ChangeSet execution behavior; clarify the review and manual-execution workflow required before implementation. Done would be an agreed product and implementation scope for production-safe updates.
