Python vs IPython: recommend %cd, %env over !cd, !export (#14629)
https://ipython.readthedocs.io/en/latest/interactive/python-ipython-diff.html#shell-assignment
The quick overview mentioned `!cd DIR` among examples of shell commands
one might use — but that doesn't work as user would hope (can only
affect commands in same ! e.g. `!cd /; pwd`).
That's not as bad now that `!cd` prints a warning, but IMHO better to
provide the right mental model up front.
=> Replaced that with minimal motivation why `!cd` and `!export` can't
work, recommending some %magic alternatives;
moved it out of examples to not distract, and right before Magics
section.
