title: Prestashop : Decorate a module's service from another module
body: <p>I want to use the module ps_facebook to send a catalog to Facebook but I need to change the name of the product sent.</p>
  <p>I already sought and I found that's the module ps_eventbus that manages to load and decorate datas.
  Unfortunately there is no hook. My only possibility is to rewrite a part of this service.
  This service is loaded by the module ps_eventbus in the file decorate.yml and I want to change the call of this service by our specific service in our module.</p>
  <p>So I wonder if it's possible to override properly the service PrestaShop\Module\PsEventbus\Decorator\ProductDecorator and how to do that ?</p>
