Wrong parameter type for the execute method in AdminActionService

[jakub-groncki]

In Vin\ShopwareSdk\Service\AdminActionService the $data parameter has type array:

class AdminActionService extends ApiService
{
    public function execute(string $method, string $path, array $data = [], array $headers = []): ApiResponse
    {
        // ...
    }
        // ...
}

But this is wrong considering the fact that some endpoints consume octet-streams.

This would need to be changed to array|string or just left as mixed by default, depending on the target PHP version.
