Hi,

I tried to reinstall monailabel in a fresh conda environment in Windows 11. Previously, I successfully installed monai and radiology app in a conda envrionment and ran in Slicer with no issue, but it suddenly could not locate the radiology app anymore.

pip install monailabel had no issue. However, installing the radiology app` monailabel apps --name radiology --download --output .` returned error below:

```auto
Using PYTHONPATH=C:\Users\chi.zhang\AppData\Local\anaconda3\envs;C:\Users\chi.zhang\SOFA\v24.06.00\plugins\SofaPython3\lib\python3\site-packages;C:\Users\chi.zhang\SOFA\external_plugins\STLIB\build\lib\python3\site-packages;
""
Traceback (most recent call last):

    return name in sorted(x.name for x in distributions())
AttributeError: 'PathDistribution' object has no attribute 'name'

```

Can someone give me some suggestions?

I found this commit [30e97b4](https://github.com/Project-MONAI/MONAILabel/commit/30e97b49ce02efd0e897c55f874b5c80bf27c7aa) and updated line 20 of monailbel/config.py. It appeared everything worked now!
