### Frontend framework

### Next.js version

Nuxt Version: 3.8.2

### Next.js router

N/A

### Describe the bug

Amplify has these Rewrites and redirects settings by default.

However, it's not working for a Nuxt SSR app, because nuxt build does not create any `index.html` file, it will keep redirecting to `/index.html` for every routes.

### Expected behavior

These settings should not be set by default for Nuxt SRR applications.

### Reproduction steps

1. Init a Nuxt 3 repo.
2. Create some pages, for example: `/login`
3. Deploy to Amplify (https://aws.amazon.com/blogs/mobile/introducing-support-for-hosting-any-ssr-app-on-aws-amplify-hosting/)
4. Visit the login page `main..amplifyapp.com/login`

It redirect to `/index.html`, since this file does not exist it will show 404 error.

### Build Settings

_No response_

### Log output

```

### Additional information

_No response_

No repository files, tests, or entry points are named. Start by reproducing the Nuxt 3.8.2 SSR deployment and inspecting the default Amplify Hosting Rewrites and redirects settings; done means a Nuxt SSR route such as /login no longer redirects to /index.html and loads successfully.
