[Bug] An error occurred when running gliner

使用 docker-compose up 启动，在label-studio 点击任务，则docker 出现报错了。

```

Start with docker-compose.yml and /app/model.py at the lazy_init call shown in the traceback. Check how /data/models/gliner_medium-v2.1 is expected to be populated and reproduce the failure with docker-compose up while observing the Hugging Face download attempt. Done means the GLiNER service can load the configured model and process a Label Studio task without the reported SSL error.
