fix(rag): Fix rerank bug of EmbeddingRetriever

[FOkvj]

Description

The EmbeddingRetriever's _aretrieve_with_score and _aretrieve methods do not pass the query parameter to the rank function when calling the ranker to re-rank the retrieval results.

How Has This Been Tested?

1. initialize a EmbeddingRetiever with the CrossEncoderRanker

retriever = EmbeddingRetriever( vector_store_connector=vector_store_connector, top_k=100, rerank=CrossEncoderRanker(topk=3), )

2. call aretrieve_with_scores

retriever.aretrieve_with_scores("what is awel talk about", 0.3)
3. debug at "/DB-GPT/dbgpt/rag/retriever/rerank.py", line 211
4. check whether the value of parameter query is None, if not, bug is fixed.

Closes #1498
