Bug when computing relavant_docs (qrels)

[tonywu71]

Description

At the following line, the relavant_docs dictionary is overridden instead of getting updated. This causes relavant_docs to only contain the last seen query. This is problematic in datasets with duplicate queries (e.g. DocVQA) as the output score is not correctly computed.

relevant_docs[query] = {queries2filename[query]: 1}
