Expose `aapply_hybrid_search_index` in PGVectorStore

[JHSeo-git]

I'm currently using langchain_postgres and found that the method aapply_hybrid_search_index is implemented in langchain_postgres/v2/async_vectorstore.py,

# langchain_postgres/v2/async_vectorstore.py

async def aapply_hybrid_search_index(
        self,
        concurrently: bool = False,
    )

but it's not exposed through the PGVectorStore interface.
Because of this, there's no way to apply the hybrid search index when working with a PGVectorStore instance created via PGVectorStore.create().

To address this, I’d like to suggest exposing aapply_hybrid_search_index on PGVectorStore:

# langchain_postgres/v2/vectorstores.py
...

+    async def aapply_hybrid_search_index(
+        self,
+        concurrently: bool = False,
+    ) -> None:
+        """Apply the hybrid search index."""
+        return await self._engine._run_as_async(self.__vs.aapply_hybrid_search_index(concurrently=concurrently))
+
+    def apply_hybrid_search_index(
+        self, 
+        concurrently: bool = False,
+    ) -> None:
+        """Apply the hybrid search index."""
+        return self._engine._run_as_sync(self.__vs.aapply_hybrid_search_index(concurrently=concurrently))

...

Thanks for the great work on this library!
