Environment details

• OS: Linux Mint 21.3
• PHP version: 8.3.14
• Package name and version: google/apiclient v2.18.1

Steps to reproduce

1. instanciate a new Google Client with a $jwt oject

$client = new Google\Client();
$jwt = new Firebase\JWT\JWT();
$jwt::$leeway = 50;

$client->setConfig('jwt', $jwt);

2. Call VerifyIdToken with the client

$client->verifyIdToken($someApiToken);

3. A 500 error is thrown
   Google\\AccessToken\\Verify::__construct(): Argument #3 ($jwt) must be of type ?string, Firebase\\JWT\\JWT given, called in \/home\/bbousba\/dev\/provider-api\/vendor\/google\/apiclient\/src\/Client.php on line 848

The error is due to the newly ?string typing in src/AccessToken/Verify.php l.72 where it should be ?Firebase\JWT\JWT

public function __construct(
    ClientInterface $http = null,
    CacheItemPoolInterface $cache = null,
    ?string $jwt = null
)

Thanks!
