Export BeforeRetryState from types/hooks

The BeforeRetryState is the only type not exported from types/hooks.

Background
We are doing an upgrade to TS 4.7, in our code we were importing the BeforeState directly like this:

import { BeforeRetryState } from 'ky/distribution/types/hooks';

However after upgrading to TS 4.7, were can no longer can import the BeforeRetryState type directly:

And since it's not export the the following does not work either:

So we want the BeforeRetryState too also be exported, so that we can import it directly e.g.:

import { BeforeRetryState } from 'ky';
