Follow Up on new wheel `torch==2.10.0+rocm710`

[michaelmckinsey1]

There are some hacks that need to be cleaned up, because the current wheel torch==2.10.0+rocm710 comes with libraries linked to cray-mpich/9.0.1 which causes segfaults. We replace the paths with paths to cray-mpich/9.1.0.

The hacks replace shared library links for libmpi_gnu_112.so.12 in .venvs/scaffoldvenv-tuo/lib/python3.11/site-packages/torch/lib/ to libmpi_gnu.so.12, which is the name for 9.1. Then in the jobscript we can LD_PRELOAD /opt/cray/pe/mpich/9.1.0/ofi/gnu/11.2/lib/libmpi_gnu.so.12 to use the correct libmpi.
