Bug#1053945: seaborn: test-failing warning in pandas 2.1

[Rebecca N. Palmer]

Control: tags -1 fixed-upstream patch
Control: severity -1 important
(Raising severity because pandas 2.x is currently blocking Python 3.12)

This looks like the upstream fix (I haven't tried it in Debian):
https://github.com/mwaskom/seaborn/pull/3355

Upgrading to upstream 0.13 would probably also work, and would be a good 
idea if it doesn't break anything else, but I haven't checked whether it 
does.
