Pull content-build output into Form Renderer app

[derekhouck]

Overview

#89918 should get us a minimally viable Form Config object from the output of content-build.

The purpose of this ticket is to take that Form Config object and slot it into the app created by #87719 to render a minimally viable form on the frontend.

Acceptance Criteria

• The Form Renderer app can render a form pulled in from content-build
• The form contains all appropriate pages/chapters as defined by the form config object it is importing
