Allow symfony 6.4 and fixing condition for valid "0" responses

[tecbird]

1. i found a bug for count api calls
   $iamAdminClient->users()->count('test', $criteria) => no user found it will return 0 (valid case)

2. symfony 6.4 should also work, we have some projects that are not currently at symfony 7.x

Thanks @tecbird and @Fahl-Design for the excellent work!
I'm sorry, but I don't feel like applying the changes to the userInfo method, so could you please remove the comma 4b44bba? Then, I'll proceed with the merge to main.

Add a new explicit method that returns the "raw" (array) representation instead of changing the userInfo signature.

I have suggested a change example.

1. Interface — Add the new method (compatible with the rest of the interface):

// src/Interface/IamClientInterface.php
public function userInfoRaw(AccessTokenInterface $token): ?array;

2. Implementation — keep userInfo, which always returns the DTO, and implement userInfoRaw, which returns the raw array:

// src/Provider/KeycloakClient.php

/**
 * @return array<string,mixed>|null
 */
public function userInfoRaw(AccessTokenInterface $token): ?array
{
    try {
        $this->verifyToken($token);
        $accessToken = new AccessTokenLib([
            'access_token' => $token->getToken(),
            'refresh_token' => $token->getRefreshToken(),
            'expires' => $token->getExpires(),
            'values' => $token->getValues(),
        ]);
        $resourceOwner = $this->keycloakProvider->getResourceOwner($accessToken);
        $user = new KeycloakResourceOwner($resourceOwner->toArray(), $token);
        $this->keycloakClientLogger->info('KeycloakClient::userInfoRaw', [
            'user' => $user->toArray(),
        ]);

        return $user->toArray();
    } 
    catch (\Exception $e) {
        $this->keycloakClientLogger->error('KeycloakClient::userInfoRaw', [
            'error' => $e->getMessage(),
        ]);

        return null;
    }
}

Here is a proposed change. Please feel free to adjust and improve it based on your expertise.
