`beforeError` hook does not return mutated error object after got 11.6.0

[piotrjaromin]

Describe the bug

• Node.js version: 12 and 14
• OS & version: Linux, ubuntu 20.10

Untill version 11.5.0 hooks.beforeError was able to return modified error instance, but after bump to 11.6.0 this is functionality is lost, error returned is always RequestError from got library.

If I am correct the overridden error comes from this line: https://github.com/sindresorhus/got/blob/49c16ee54fb19ea7aa77e24ac8c2b602f0aad265/source/core/index.ts#L2708

Actual behavior

errors returned by before hook are NOT propagated to caller

Expected behavior

errors returned by before hook propagated to caller

Code to reproduce

const got = require('got');

class CustomError extends Error {}

got('https://api.github.com/some-endpoint', {
    hooks: {
        beforeError: [err => {
            console.log('Mapping to custom one:', err.message);
            return new CustomError();
        }],
    },
})
    .then(() => console.log('Error was not thrown')) // <- will not be logged
    // Below line for got:
    // 11.5.0: Got error: CustomError
    // 11.6.0: Got error: RequestError
    .catch(err => console.log('Got error:', err.constructor.name));
...

Checklist

• [x] I have read the documentation.
• [x] I have tried my code with the latest version of Node.js and Got.

I have exactly the same actual/expected behavior on:

• NodeJS 12/14
• MacOS Mojave 10.14

I agree that it would be great to see this feature. There is already an issue about this.
