[Bug] DDL error from SSL

- [ ] I didn't find a similar issue already open.
- [ ] I read the documentation (README AND Wiki)
- [ ] I have installed FFMpeg
- [ ] My problem is related to Spleeter only, not a derivative product (such as Webapplication, or GUI provided by others)

## Description

I'm getting a DLL error after following the installation instructions by order.

## Step to reproduce

1. Installed using the following:
'
conda install -c conda-forge ffmpeg libsndfile
pip install spleeter
'
2. Run Jupyter notebook from visual studio code, use the command
'!spleeter separate -o ./output ./tmp/audio_example.mp3'

3. Got error

## Additional context

At the other (different) closed issues involving DLLs I haven't found direct solution to the problem.

Start by reproducing the Windows 10 installation with `conda install -c conda-forge ffmpeg libsndfile` and `pip install spleeter`, then run the reported Jupyter command. Trace the failure through `spleeter/model/provider/github.py`, `httpx`, `httpcore`, and Python's `ssl.py`; done means the example separation command runs without the `_ssl` DLL error.
