On updating ipython to upstream 7.29.0

[Julien Puydt <julien.puydt@gmail.com>]

Hi,

I tried to update ipython to latest upstream. I fixed some things here
and there but there's still :

1) Building the doc, some files don't get found (several no such file
or directory docs/source/whatever/file) and a few syntax errors,
perhaps due to the previous issues -- strangely, that doesn't make the
build fail!


2) Running autopkgtest doesn't work (and that's why I pushed to salsa
but didn't upload):

I'm not sure the failure isn't due to my running the autopkgtest with a
schroot sbuild...

I'll try to dig further, but in the meantime if someone has a clue, I'm
all ears!

Cheers,
