fix: remove empty ACE Step workflow placeholders

Removed 3 empty placeholder workflows that only contained metadata:
- acestep-multilang-t2m-v1.json
- acestep-remix-m2m-v1.json
- acestep-chinese-rap-v1.json

Kept only the functional workflow:
- acestep-simple-t2m-v1.json (6 nodes, fully operational)

Users can use the simple workflow and modify the prompt for different use cases:
- Multi-language: prefix lyrics with language tags like [zh], [ja], [ko]
- Remixing: load audio input and adjust denoise strength (0.1-0.7)
- Chinese RAP: use Chinese RAP LoRA with strength 0.8-1.0
