Delba de Oliveira 0b35ddd825 Docs: Move next.config.js API pages under a config folder, fix headings in TS and ESLint config pages (#72465)
This PR:

- Moves `next.config.js` options under a "config" folder which includes
references for other configuration such as the ESLint plugin. I figure
it would be tidier than having "Next.config.js Options" and "Config" in
the API reference.
- Fixes the issue with the "config" folder not showing up in canary:

- Fixes the indentation issues and missing example header (caused by an
invisible character).

title: The provided export path doesn't match the page.

## Why This Error Occurred
An `exportPathMap` path was improperly matched to a dynamically routed page.
This would result in the page missing its URL parameters.
## Possible Ways to Fix It
Change your `exportPathMap` function in `next.config.js` to have a path that matches the dynamically routed page.
```js filename="next.config.js"
module.exports = {
exportPathMap: function () {
return {
'/': { page: '/' },
// '/blog/nextjs': { page: '/blog/[post]/comment/[id]' }, // wrong
'/blog/nextjs/comment/1': { page: '/blog/[post]/comment/[id]' }, // correct
}
},
}
```
