[Platform][VertexAI] Invalid service config

[1ed]

Hi, I tired to use Vertex AI:

ai:
    platform:
        vertexai:
            location: '%env(GOOGLE_CLOUD_LOCATION)%'
            project_id: '%env(GOOGLE_CLOUD_PROJECT)%'

but I've got

Unable to dump a service container if a parameter is an object or a resource, got "Symfony\Component\HttpClient\EventSourceHttpClient".

it seems it comes from

ff296bf#diff-f2828d6c9ecf4603ca1695c4958952ae24994a6e697e0a6e5b57f7f1c336ee47R261-R267

We should define a factory here instead, don't we?
