Basic user@pass is dropped (worked in 2.6.1)

[GrosSacASac]

I didn't see it mentioned in the upgrade guide

Reproduction

Steps to reproduce the behavior:

1. Create an url that contains a user and password
2. use fetch
3. look at what was sent
4. (Basic http header is missing)

import fetch from "node-fetch";

if (!globalThis.fetch) {
    globalThis.fetch = fetch;
}


const baseUrl = `https://XXX:YYY@letz.social/echo-test/zzz`;

fetch(baseUrl, {
    headers: {
        Accept: `application/json`,
    },
}).then(response => {
    if(!response.ok) {
        throw response.statusText;
    }
    return response.text();
}).then(text => {
    console.log(text);
});

Observed behavior (3.0.0)

node test.js
/echo-test/zzz    Method: GET

    Headers:

Host: letz.social
Connection: close
accept: application/json
accept-encoding: gzip,deflate,br
user-agent: node-fetch

    Body:

Expected behavior (2.6.5)

node test.js      
/echo-test/zzz    Method: GET

    Headers:

Host: letz.social
Connection: close
Accept: application/json
User-Agent: node-fetch/1.0 (+https://github.com/bitinn/node-fetch)
Accept-Encoding: gzip,deflate

we decided to completely drop support for it in #1268 it now throws an error if you try to construct a Request with a auth-url (doe it's not released)
the solution is to do basic auth header

... Should update the docs
