[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.

Inizia dalla pagina di installazione di React Compiler e dal repository react-vite-compiler-repro collegato. Esamina la configurazione del plugin Babel personalizzato per Vite e la relativa babelConfig, quindi verifica se sourceMaps: true risolve la differenza di sourcemap segnalata prima di aggiornare le istruzioni di installazione, se confermato.
