Aligned doc output format with repro scripts

[wu-ming233]

Aligned regression documentation output format with the repro scripts. The unified format is:

run.collection-name.condition-name.topic-name.txt

where collection-name in {"msmarco-v2.1-doc", "msmarco-v1-passage", "beir"}, condition-name is specified in the yaml files under src/main/resources/reproduce, and topic-name is specified by the corpus.

Additionally, the repro scripts now run the same amount of cases as in the documentation.
