653ac837 - Prevent typescript errors in IDE for newly generated tests (#78247)

Prevent typescript errors in IDE for newly generated tests (#78247) When generating a new test with `pnpm new-test`, the IDE will show the following error when opening the generated `page.tsx` or `layout.tsx` files: ```sh 'React' refers to a UMD global, but the current file is a module. Consider adding an import instead.ts (2686) ``` This is because by default, the generated test app is covered by the root `tsconfig.json`, containing `{"jsx": "react-jsx"}` which expects there to be a `React` import that the template files don't have. When first running `pnpm next dev` or `pnpm next build`, a local `tsconfig.json` file is generated for the test app. This config contains `{"jsx": "preserve"}`, which fixes the initial errors. To avoid this step, and prevent the initial compiler errors, we can just copy the `tsconfig.json` as well as the `next-env.d.ts` from the CNA template files into the new test app. (Those two files are git-ignored, by the way.)
