Subject: [PATCH] Document vectorize_collection_name as having no effect on
 multi2vec factories

The parameter is accepted by all eight multi2vec_* factories and passed to
none of them: every factory drops it before building its config object, so
it never reaches the server. multi2vec_voyageai and multi2vec_nvidia already
document it as deprecated. This applies the same wording to the other six.

Server side, no multi2vec module reads the setting. The reader lives on
BaseClassSettings, and its two production consumers (ValidateIndexState, via
BaseClassSettings.Validate, and object_texts.go's TextsWithTitleProperty) sit
on paths the multi2vec modules never enter: they implement their own
Validate() that calls ValidateMultiModal, and the six that hold an
ObjectVectorizer never call a method on it.
