New issue by Eloitor on void-packages repository

https://github.com/void-linux/void-packages/issues/49402

Description:
### Is this a new report?

Yes

### System Info

Void 6.6.22_1 x86_64 GenuineIntel uptodate hold rFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

### Package(s) Affected

python3-3.12.2_2, jupyterlab-4.0.12_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

https://github.com/marimo-team/marimo/issues/968

### Expected behaviour

I install a package in a python venv following the instuctions from 
and after activating it I can use it in jupyter lab. https://github.com/void-linux/void-packages/issues/47135#issuecomment-1826828577

This worked for me before but no longer works??? I don't know what happened...

### Actual behaviour

An installed package with venv is available to use in jupyter lab (after activating the environment)

### Steps to reproduce

1. Install jupyterlab
```
python -m venv --system-site-packages ~/venv
git clone https://github.com/gdamjan/hello-world-python-package.git
cd hello-world-python-package
~/venv/bin/pip install -e .
cd ..
. ~/venv/bin/activate
jupyter lab
```

In jupyter lab

```
from cool_lib import a
```

`~/venv/bin/python -m ipykernel install --name my_cool_venv` and it will show up as a kernel

Thanks!! This works with `jupyter lab` very cool trick to be able to use kernels with custom environments!

However this trick does not work with marimo as it does not use ipython. #48818 

This worked before, but I'm very surprised that it doesn't work now....

mmm... runing `python -m marimo edit test.py` works. But before I only needed `marimo edit test.py`

Comment:
This is expected behavior. When packages are built with `xbps-src`, the shebang in Python scripts is deliberately overwritten to use `/usr/bin/python3` instead of whatever Python interpreter might be in your path. Hence, running `jupyter` will ignore the virtual environment. We do this to ensure that Void-packaged Python scripts behave in a predictable manner.

If you want to override the shebang in Void-packaged scripts, you'll have to explicitly run the interpreter. You can write a wrapper or define an alias to make this happen.

Comment:
This makes sense, but it is very strange too, because I was using this until yesterday when it stopped working...
