Add PyJulia package in julia-notebook and datascience-notebook

[i0ntempest]

What docker image(s) is this feature applicable to?

julia-notebook

What change(s) are you proposing?

Add PyJulia package to julia-notebook and datascience-notebook

How does this affect the user?

PyJulia allows calling julia from python, which is very useful when using this notebook with Open WebUI where models can only call Python.

Anything else?

PyJulia doesn't seem to be supported anymore: https://github.com/JuliaPy/pyjulia#pyjulia:

Ongoing development of the Python/Julia interface has transitioned to PythonCall.jl/juliacall, please consider using that package instead.

So, I don't think we will be adding PyJulia.

But we might add https://github.com/JuliaPy/PythonCall.jl, could you please create a PR where you add this package?
It would be great, if you added a test that it works as well

Just saw that - that package would be even better. I'm not familiar with composing docker images, but I'll try adding packages to a running image and report back.

@i0ntempest I would be glad if you created a PR for your suggestion

To do that you need to:

1. Add a package here: https://github.com/jupyter/docker-stacks/blob/main/images/minimal-notebook/setup-scripts/setup-julia-packages.bash#L34
2. A a simple test here: https://github.com/jupyter/docker-stacks/tree/main/tests/image_specific_tests/julia-notebook
3. Take a look at our policy when we add new packages: https://jupyter-docker-stacks.readthedocs.io/en/latest/maintaining/new-images-and-packages-policy.html. It's mostly for maintainers, but still worth taking a look at.
4. Update: https://github.com/jupyter/docker-stacks/blob/main/docs/using/selecting.md
