Subject: [PATCH] Fix typo in VectorStoreIndexWrapper method (#1922)

Fixed a typo in the argument of the query method within the
VectorStoreIndexWrapper class. Specifically, the argument `retriver` has
been changed to `retriever`. With this correction, the correct argument
name is used, and potential bugs are avoided.
