Update dependencies

[jl-wynen]

The build currently fails with the latest package versions. We should update everything and fix all issues.

Concretely, I got this from the powder analysis notebook:

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
Cell In[1], line 2
      1 import numpy as np
----> 2 from easyscience.Objects.variable import Parameter
      3 from easyscience.Objects.ObjectClasses import BaseObj
      4 from easyscience.fitting import Fitter

ModuleNotFoundError: No module named 'easyscience.Objects'

We have some packages here that are not on VISA. (e.g. corner) Do we add those to the regular visa env or do we make a dedicated school env? @MridulS

We make a new env like last year: https://git.esss.dk/visa/visa-pixi-env/-/commit/f2c9a508c49430da320b0ab4339b901ef6a340f2
