py-ipython: updated to 8.18.1

IPython 8.18 and 8.18.1
-----------------------

8.18.1 is identical to 8.18 but pin ``prompt_toolkit`` to greater than ``3.0.41``

Small release of IPython that fixes a small number of inconveniences.

 - :ghpull:`14251` Fix a memory leak in qt event loop integration by setting
   the Loop parent to None.
 - :ghpull:`14252` Pickleshare was made an optional dependency in 8.17, this
   leads to warnings in some installations when using modules completions. The
   warning has been silenced.
 - :ghpull:`14241` Update event loop code for compatibility with more recent
   ``prompt_toolkit`` due to deprecations in Python 3.12.
 - :ghpull:`14245` Fix doc example on Pygments styles
 - :ghpull:`14238` Remove dependency on app_nope, this is actually only a
   dependency of IPykernel.
