Documented Format For View Hierarchy Json File

### Problem Statement

It'd be nice if the structure of the view hierarchy file was documented or an example was provides on the [documentation page](https://docs.sentry.io/platforms/android/enriching-events/viewhierarchy/) so that I could cobble together a version of this file for our macOS application.

### Solution Brainstorm

Attaching an example file, or showing a snippet on the page would be helpful enough to let people fill in the blanks as needed!

### Are you willing to submit a PR?

Sure, if you let me commit to your documentation :)
