Unsatisfiable requirements detected for package ModelingToolkit, compatibility issue in the BaseModelica.jl CI workflow

Description
Currently BaseModelica.jl fails on master due to a compatibility issue (https://github.com/OpenModelica/OpenModelicaLibraryTesting/actions/runs/21692216451/job/62554444959)

  Unsatisfiable requirements detected for package ModelingToolkit [961ee093]:
   - restricted to versions 11 by BaseModelica [a17d5099] (fixed to v1.4.0)
   - restricted to versions 10 by TestBaseModelica [bba3f925] (fixed to v0.1.0)

Solution
Update the Project.toml file to fix the dependencies

I'll attempt to solve this issue quickly

Solved in PR #268

The Jenkins test job is still struggling:

I update Julia on the test server to v1.12.5. I update the Manifest.toml to one generated with the same Julia version.
I'm not sure what's the issue here. Maybe we need to update BaseModleica.jl before running any other stuff like Pkg.add("PackageCompiler"). I hope this works for now, but these scripts are a hot mess.

I hope this helps: https://test.openmodelica.org/jenkins/blue/organizations/jenkins/LibraryTesting%2FLibraryTest/detail/LibraryTest/10563/pipeline

It did not, so let's nuke Manifest.toml altogether. Who needs reproducibility anyway.

Hmm, I suppose I can check it out again

The issue was the juliacall package. It's a Python package that brings a Julia installation itself. While the installed version of Julia is v1.12.5 it requires an older version which is incompatible with the installed Julia SSL package. Therefore we see

           | ])
           | Pkg.resolve()
           | Pkg.precompile()

I update juliacall (now it needs 1.10.3 - 1.11) and purged already installed / compiled Julia packages. Now I can run

>>> from juliacall import Main as jl

We really really need to containerize these tests.

We really really need to containerize these tests.

👍
If you're restructuring, I'd appreciate if OpenModelicaLibraryTesting can remain "generically" usable for testing packages, without optional Julia etc. (Right now I'm on a really old version, I'll have to do another attempt at updating at some point)
