Add improvements for Godot View Hierarchy

[limbonaut]

I'm working on the Sentry SDK for Godot Engine, and we're adding support for View Hierarchy feature as described in the RFC. You can check it out in the following PR:

• feat: View Hierarchy sentry-godot#143

We’d like to make some changes to the Sentry UI just for the Godot SDK. Here’s a visual guide:

Requested changes:

• Change header from "View Hierarchy" to "Scene Tree".
• Hide or remove the right section since it's not needed for our use-case.
• Use the name attribute from the JSON attachment for hierarchy item text.
• Show icon of the Godot Engine on the left side.

Rendering system is specified as Godot in the JSON file. For reference: view-hierarchy.json and issue example.

I kept the JSON attributes named as the properties are named in the Godot Engine (check the links below):

• name of a scene tree node - it is guaranteed to be unique within the same level of hierarchy
• class corresponds to the core class of a scene tree node.

If needed, I can rename one or both to identifier and type as suggested in RFC. However, those two would be less recognizable for users.

Here's how it looks in Godot Engine:
