license: apache-2.0

I'll fetch the README content from the HuggingFace model page first. The README for libryo-ai/colbertv2.0 is essentially empty — it only contains the license metadata:

---
license: apache-2.0

翻译后的内容：

---
license: apache-2.0

(Note: The license field apache-2.0 is a standard identifier and should not be translated.)
