Headers no longer available at beforeRedirect

[yli-hallila]

Describe the bug

Prior to PR #4708 you could access redirect headers with beforeRedirect: (options, { headers }) but with the changes in #4708 the headers are no longer available. To me it's unclear whether this was an intentional change or not but the documentation suggests that this should still be working.

To Reproduce

https://npm.runkit.com/axios

var axios = require("axios")
// Works with an older version
// var axios = require("axios@0.27.2")
var express = require("express")
var app = express()

app.get('/redirect', (req, res) => {
  res.cookie("Hello", "World");
  res.redirect("/");
})

app.get('/', (req, res) => {
  res.send('Hello World!')
})

app.listen(3000, () => {
    axios.get("http://localhost:3000/redirect", {
        // Headers undefined
        beforeRedirect: (options, { headers }) => {
            console.log({options, headers});
        }
    });
});
