Subject: [PATCH] Move `ExtractInstancesPlugin<EnvironmentMapIds>` init to app.
 (#19867)

# Objective

- This plugin currently does nothing. That's because we add the plugin
to the `RenderApp`. Inside the plugin it then looks for the `RenderApp`
itself, but since it was added **to** the `RenderApp`, it will never
find the `RenderApp`.

## Solution

- Move the plugin into build, and more importantly, add it to the app
not the render_app.
