Delete or update semantic entries

With the current implementation, it's possible to use the learn method in the SemanticSearch component to generate a SemanticEntry in our vector store, but we don't have a way to delete or update them.

I'd propose to add update and delete, or maybe a forget method to remove a semantic entry from the database.

I envision this as two different methods deleteWithId and forget.

The first one deletes the one with the specified ID, while the other one deletes the closest one semantically to that phrase.

I don't know if that makes sense.

I'd only allow deleting with id. A method that deletes "The semantically closest record" could have quite unpredictable results 😅
