A good fit is Label Studio.
It supports:
- Entity extraction / NER annotation
- Multilingual document annotation
- Label schema versioning through project configuration history and label config management
If you want, I can also list a few alternatives and compare them on schema versioning, multilingual support, and NER workflow support.
