fix(@angular-devkit/build-angular): pre-transform error when using vite with SSR

This commit fixes a regression which causes a pre-transform error when using vite with ssr. The `request.url` is now passed to the index transformer instead of `request.originalUrl`. This is because the `request.url` will have a value of the `index.html`.

Closes angular#26897
