Update dependencies for node-fetch v3.x

[TimothyGu]

After #488 we will have two packages (nyc, whatwg-url) pinned to an older version due to the fact that the new version does not support Node.js v4.x, and another one (url-search-params) required only for Node.js v4.x as newer versions of Node.js support URLSearchParams. We should update the list of dependencies for node-fetch v3.x, which will drop compatibility for Node.js v4.x.

According to the docs URLSearchParams was only added in Node.js 7.5, the polyfill would still be required when the minimum version is Node.js 6.

@realityking It’s been backported to v6.x (see https://github.com/nodejs/node/pull/17365)… the docs just need to be updated to reflect that

Are we going to remove the dependencies and simply just use the builtin?

import { URL, URLSearchParams } from 'url'

The dependencies are updated in 3.x
