When rendering richText component on frontend, titleEn/Fr should not be rendered

## Description
Had a template that somehow had text in a titleFr property of a richText element. RichText elements only use the descriptionEn/Fr properties for content. Not sure how the text got there, but one problem is that when rendering the frontend form, the text in titleFr was being rendered to screen. We should not render titleEn/Fr on richText elements.

## Steps to reproduce
See attached form file. There is one richText element with some text in the titleEn/Fr properties. Load the form, see the text that should not be displayed.

[test-2025-12-12.json](https://github.com/user-attachments/files/24134327/test-2025-12-12.json)

Start with the attached test-2025-12-12.json and load it in the frontend to reproduce the richText rendering issue. Trace the richText component or rendering entry point, then verify that titleEn/titleFr are not displayed while descriptionEn/descriptionFr remain visible.
