community[patch]: Implement similarity_score_threshold for MongoDB Vector Store (#14740) 
Adds the option for `similarity_score_threshold` when using
`MongoDBAtlasVectorSearch` as a vector store retriever.

Example use:

```
vector_search = MongoDBAtlasVectorSearch.from_documents(...)

qa_retriever = vector_search.as_retriever(
    search_type="similarity_score_threshold",
    search_kwargs={
        "score_threshold": 0.5,
    }
)

qa = RetrievalQA.from_chain_type(
	llm=OpenAI(), 
	chain_type="stuff", 
	retriever=qa_retriever,
)

docs = qa({"query": "..."})
```

I've tested this feature locally, using a MongoDB Atlas Cluster with a
vector search index.
