Fixes: #13512
Defined and exported type for `metric` used in [reportWebVitals](https://nextjs.org/docs/advanced-features/measuring-performance)
```
export function reportWebVitals(metric) {
if (metric.label === 'custom') {
console.log(metric) // The metric object ({ id, name, startTime, value, label }) is logged to the console
}
}
```
One can now do
```
import { NextWebVitalsMetric } from 'next/app'
export function reportWebVitals(metric: NextWebVitalsMetric ) {
if (metric.label === 'custom') {
console.log(metric) // The metric object ({ id, name, startTime, value, label }) is logged to the console
}
}
```

Closes https://github.com/vercel/next.js/issues/14500
Our current docs for `next/router` use examples from both `useRouter` and `import Router from 'next/router'`, with this PR I'm unifying the API into `useRouter` (`withRouter` is still going to be mentioned multiple times as it is the HOC alternative) and no longer mentioning that you can import a global `Router` object from `next/router`, not sure if I should mention it at least once but that didn't seem to be required.
I also did some structural changes to the docs for `next/router`, now every method starts with a description, then the implementation and explanation of the parameters of the method, and then the usage example, because every method uses the same `Usage` title the hash for them would be something like `#usage`, `#usage-1`, `#usage-2`, e.t.c, so I'm not very happy with this but it looks good.

The [docs for customising the PostCSS config](https://nextjs.org/docs/advanced-features/customizing-postcss-config) warn the user they will need to manually install any dependencies that Next.JS will implicitly use if the config is not overridden. `postcss-preset-env` is missing from the install command.
