Reduce logging in the leaderboard #2333
Description
Currently there is extensive logging in the leaderboard. That makes it hard to spot actual errors.
I would resolve warnings where possible, potentially prevent some warning and / reduce the severity of some warnings from warnings to info (if they are indeed info).
Notably I would solve:
/mteb/mteb/leaderboard/figures.py:222: FutureWarning:
Downcasting behavior in `replace` is deprecated and will be removed in a future version. To retain the old behavior, explicitly call `result.infer_objects(copy=False)`. To opt-in to the future behavior, set `pd.set_option('future.no_silent_downcasting', True)`
