[Typo]: React Compiler Vite installation docs with "vite-plugin-babel" cause sourcemap issues

Summary

When following the setup instructions for React Compiler on the current live docs site, if using a custom Vite Babel plugin + React SWC or React Router v7 framework mode, you will notice that if a component gets optimized by React Compiler, the sourcemaps appear to have some React Compiler-optimized code paths in them, making dev debugging more difficult.

Happy to dig into this more, but hoping that it's as simple as just turning the relevant sourcemaps option ON for the custom Vite Babel plugin. I ran into this converting a RRv7 framework mode repo to add React Compiler, and the instructions seem to leave out sourceMaps: true in babelConfig.

Commencez par la page d’installation de React Compiler et le dépôt react-vite-compiler-repro indiqué. Examinez la configuration du plugin Babel personnalisé pour Vite et sa babelConfig, puis vérifiez si sourceMaps: true résout la différence de sourcemap signalée avant de mettre à jour les instructions d’installation si cela est confirmé.
