Fix a bug in doctrine.yaml configuration

[DominikStyp]

Without this i had an error when I tried to use following configuration in config/doctrine.yaml:

        result_cache_driver:
            type: php_file

This should be possible to use because it's implemented, but it's not included in SymfonyBridgeAdatper.php and configuration.

This bundle became deprecated

Please be aware that this bundle became deprecated and won't be compatible with Symfony 5 and upwards.
Read more about the deprecation and the alternatives for this bundle in the issue

Thanks for the PR! However, we're not accepting any new features, as the bundle is deprecated and will be archived after a bug fixing phase for the current minor release.
