Each child in a list should have a unique "key" prop.

```

Which components are affected?
Apparently the warning appears for every node where there are more than 1 children. That goes for normal components as well as plain jsx.

A full error log:
```text
hydration-error-info.js?7847:27 Warning: Each child in a list should have a unique "key" prop. See https://reactjs.org/link/warning-keys for more information.

### Config

```javascript
module.exports = {
reactStrictMode: true,
experimental: {
appDir: true,
swcPlugins: [
[ 'next-superjson-plugin', {} ]
]
},
async redirects() {
return [
{
source: '/',
destination: '/documents',
permanent: true,
},
]
},
transpilePackages: ['ui'],
};
```
