Fix agent_version display and make Overall Score bold

- Fixed case mismatch in simple_data_loader.py: 'openhands version' -> 'Openhands version'
- Fixed case for 'Language model' -> 'Language model' to match transformer expectations
- Modified format_score_column to make Overall Score values bold
- Overall Cost remains non-bold as requested
