Pull Request Overview

This PR removes deprecated sx prop documentation entries from component documentation JSON files. The sx prop (of type SystemStyleObject) was previously deprecated but still documented. This cleanup aligns the documentation with the actual component interfaces, which no longer support the sx prop.

Key Changes:

• Removed deprecated sx prop documentation from UnderlinePanels and its subcomponents
• Removed deprecated sx prop documentation from deprecated components (UnderlineNav, FilteredSearch)
