[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.

从 React Compiler 安装页面和链接的 react-vite-compiler-repro 仓库开始。检查自定义 Vite Babel 插件的设置及其 babelConfig，然后验证 sourceMaps: true 是否能解决报告的 sourcemap 差异；如果确认可以，再更新安装说明。
