write documentation requiring React components to have .jsx extension instead of .js

[aqandrew]

Dependency

• Merge: #1778

Overview

As a consequence of our Vite migration, we need to document the necessity for components to have .jsx file extensions

More Info

Traditionally, React components may be written in either .js or .jsx files. Our new build tool, Vite, requires that all files containing React components have the .jsx extension. This practice helps to prevent errors during Vite's static analysis of imported files.

Action Items

• create new wiki page: "Vite Migration: Why Vite Components Require JSX Extensions"
