Replace references to Goutte with HttpBrowser

With the introduction of [HttpBrowser](symfony/symfony#30602) there's no need for Goutte any more, but the docs currently mention both, which is a little bit confusing. Also, the current version of Goutte actuality [extends HttpBrowser](https://github.com/FriendsOfPHP/Goutte/blob/v4.0.0/Goutte/Client.php), but doesn't add any functionality to it. It seems to me that Goutte is being completely replaced with HttpBrowser so there's no point in mentioning it in the docs any more.
