[Feature Request]: Qdrant BM25 native support

[daradib]

Feature Description

Qdrant introduced native support for BM25 sparse embeddings in v1.15.2 (qdrant/qdrant#6891). qdrant-client is adding support for it as well (qdrant/qdrant-client#1060).

Value of Feature

Currently using QdrantVectorStore for hybrid search requires FastEmbed, but with built-in BM25 support, FastEmbed would not longer be needed for sparse embeddings. This would make the client much lighter and performant, similar to other vector stores like Milvus.
