[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.

從 React Compiler 安裝頁面和連結的 react-vite-compiler-repro 儲存庫開始。檢查自訂 Vite Babel 外掛程式的設定及其 babelConfig，然後驗證 sourceMaps: true 是否能解決回報的 sourcemap 差異；如果確認可以，再更新安裝說明。
