SocialiteManager 缺少 Readme 中说明的 (g|s)etRequest

[Moln]

Readme说明中有提到 getRequest , setRequest 。实际并未提供。

https://github.com/overtrue/socialite#custom-session-or-request-instance

$request = new Request(); // or use AnotherCustomRequest.
$socialite = new SocialiteManager($config, $request);
$socialite->setRequest($request);
$request = $socialite->getRequest();
