Remove reference to anaconda/3 module
Description
This module load command fails on EL9. It has been unnecesary since we switched to launching Python with an absolute path back in 2020. But it also hasn't been a problem until now, and we don't look at this script very often, so it's just been left there.
How Has This Been Tested?
To be tested in CI. But if anything was still using the Python 3.6 Anaconda installation set up by DESY, I think we'd have run into problems before now.
