Use JSX in display names of the `TypeScript React` and `JavaScript React` languages (#168368)

Use JSX in display names of the TypeScript React and JavaScript React languages

Fixes #138285

This changes the display name of the languages `JavaScript React` -> `JavaScript JSX` and `TypeScript React` -> `TypeScript JSX`

This only changes the display names and leaves the ids alone. Changing the ids would be a very breaking change for extensions with no real user benefits
