py-ipython: updated to 8.8.0

IPython 8.8.0
-------------

First release of IPython in 2023 as there was no release at the end of
December.

This is an unusually big release (relatively speaking) with more than 15 Pull
Requests merge.

Of particular interest are:

 - :ghpull:`13852` that replace the greedy completer and improve
   completion, in particular for dictionary keys.
 - :ghpull:`13858` that adds ``py.typed`` to ``setup.cfg`` to make sure it is
   bundled in wheels.
 - :ghpull:`13869` that implements tab completions for IPython options in the
   shell when using `argcomplete <https://github.com/kislyuk/argcomplete>`. I
   believe this also needs a recent version of Traitlets.
 - :ghpull:`13865` makes the ``inspector`` class of `InteractiveShell`
   configurable.
 - :ghpull:`13880` that remove minor-version entrypoints as the minor version
   entry points that would be included in the wheel would be the one of the
   Python version that was used to build the ``whl`` file.

In no particular order, the rest of the changes update the test suite to be
compatible with Pygments 2.14, various docfixes, testing on more recent python
versions and various updates.
