[bug#28782] [PATCH] gnu: Add python-jupyter-console as input to python-ipython.

[Christopher Baines <mail@cbaines.net>]

This fixes running ipython console and ipython3 console.

As python-ipython is an input to python-jupyter-console, depend on a modified
version of the package which doesn't have this input.

* gnu/packages/python.scm (python-ipython)[propagated-inputs]: Add a modified
  version of python-jupyter-console.
