Configure Stack Trace Rules from Sentry API

### Problem Statement

When I create a new Sentry project using the API, I would like to be able to configure its Stack Trace Rules the same way.
Using the API to list an existing project, I can see the Stack Trace Rules configuration stored under the `groupingEnhancements` property.
I could not find a way to update it programmatically in the Sentry API documentation: https://docs.sentry.io/api/projects/

### Solution Brainstorm

_No response_

### Product Area

Projects - Project Creation

Start with the Projects API documentation and the existing project's groupingEnhancements property described in the issue. Trace the project creation and update API entry points, then define and document a request that configures Stack Trace Rules and verify that the setting is reflected when the project is retrieved.
