[LiveComponent] fix: LiveComponentHydrator::hydrateValue() cannot hydrate null values

[nikophil]

Hello,

such live prop cannot currently be hydrated by LiveComponentHydrator::hydrateValue() because nullability is not handled and the serializer is asked to deserialize null into MyDTO

    #[LiveProp(writable: true, useSerializerForHydration: true)]
    public ?MyDTO $myDTO = null;

this PR fixes this problem

NB: all the failures in the CI are unrelated to this fix
