Per Page translation is available ?

i'm sorry but the  withLocalesStaticPaths function customization : 
```ts 
export const getStaticPaths = withLocalesStaticPaths(() => ({
  paths: ['/example', '/hello/world'],
  fallback: false,
}));
```
suggests that you can do a per page translation but there's no example for the translation folder contents that might have them. if you can provide an example it will be helpful.
