Fix Warning: Undefined array key on PHP8

[babeuloula]

Hello,

With PHP8.1 and Symfony 6.0 I've got an error when I tried to call getName method.

/** @var KeycloakResourceOwner $keycloakUser */
$keycloakUser = $client->fetchUserFromToken($accessToken);

$keycloakUser->getName(); // Warning: Undefined array key "name"

Have a nice day.
