Comment:
For some reason, I struggle to pick up this kernel in jupyterlab.
I wonder if we need something similar to what Arch has
```
# fix symlinks to assets
  _pythonpath=`python -c "from sysconfig import get_path; print(get_path('platlib'))"`
  for _i in $(ls "$srcdir"/sage-$pkgver/src/sage/ext_data/notebook-ipython); do
    rm "$pkgdir"/usr/share/jupyter/kernels/sagemath/$_i
    ln -s $_pythonpath/sage/ext_data/notebook-ipython/$_i "$pkgdir"/usr/share/jupyter/kernels/sagemath/
  done
```
