Can't run openmc example

[RemDelaporteMathurin]

I created a clean env today and tried to run the openmc example and got:

Traceback (most recent call last):
  File "/home/remidm/FESTIM-v2-review/coupling/coupling_neutronics/openmc_example.py", line 155, in <module>

this should be fixed by #festim-dev/openmc2dolfinx#9

I still can't run this example after installing a fresh version of the environment.

Get the following error:
