py-ipython: updated to 7.11.1

IPython 7.11.1
==============

A couple of deprecated functions (no-op) have been reintroduces in py3compat as
Cython was still relying on them, and will be removed in a couple of versions.

IPython 7.11
============

IPython 7.11 received a couple of compatibility fixes and code cleanup.

A number of function in the ``py3compat`` have been removed; a number of types
in the IPython code base are now non-ambiguous and now always ``unicode``
instead of ``Union[Unicode,bytes]``; many of the relevant code path have thus
been simplified/cleaned and types annotation added.

IPython support several verbosity level from exceptions. ``xmode plain`` now
support chained exceptions. :ghpull:`11999`

We are starting to remove ``shell=True`` in some usages of subprocess. While not \ 
directly
a security issue (as IPython is made to run arbitrary code anyway) it is not good
practice and we'd like to show the example. :ghissue:`12023`. This discussion
was started by ``@mschwager`` thanks to a new auditing tool they are working on
with duo-labs (`dlint <https://github.com/duo-labs/dlint>`_).

Work around some bugs in Python 3.9 tokenizer :ghpull:`12057`

IPython will now print its version after a crash. :ghpull:`11986`

This is likely the last release from the 7.x series that will see new feature.
The master branch will soon accept large code changes and thrilling new
features; the 7.x branch will only start to accept critical bug fixes, and
update dependencies.
