Cannot enable doctrine for api_platform

It is currently impossible to enable doctrine based entities for api platform, as the config option api_platform.doctrine.enabled ist overwritten in the function Dbp\Relay\CoreBundle\DependencyInjection\DbpRelayCoreExtension::prepend by calling $container->loadFromExtension

This calls need to be changed to $container->prependExtensionConfig as documented in https://symfony.com/doc/5.2/bundles/prepend_extension.html
