Issue creating CESM case with visualCaseGen cime_interface

[manishvenu]

In the CrocoDash workflow, it calls visualCaseGens cime_interface, which calls self._retrieve_machines, which calls CIME.XML.machines Machines class for every machine available (Lines 618 onward). In the initialization for the Machines class, it validates the xml files for each machine. On the "casper" machine, this fails with the error, "

E CIME.utils.CIMEError: ERROR: Command: '/usr/share/miniconda/envs/CrocoDash/bin/xmllint --xinclude --noout --schema /home/runner/work/CrocoDash/CrocoDash/CESM/cime/CIME/data/config/xml_schemas/config_machines_version3.xsd /home/runner/work/CrocoDash/CrocoDash/CESM/ccs_config/machines/casper/config_machines.xml' failed with error '/home/runner/work/CrocoDash/CrocoDash/CESM/ccs_config/machines/casper/config_machines.xml:19: Schemas validity error : Element 'GPU_TYPE': This element is not expected. Expected is one of ( MAX_CPUTASKS_PER_GPU_NODE, MPI_GPU_WRAPPER_SCRIPT, COSTPES_PER_NODE, PROJECT_REQUIRED, mpirun ).
E /home/runner/work/CrocoDash/CrocoDash/CESM/ccs_config/machines/casper/config_machines.xml fails to validate' from dir '/home/runner/work/CrocoDash/CrocoDash/CrocoDash'

"

This only occurs when using Github Actions with machine ubuntu-latest and does not occur on derecho/casper. Sample action: https://github.com/CROCODILE-CESM/CrocoDash/actions/runs/13398159162/job/37422549889

I looked into this further, the current ESCOMP/CESM has a cime commit that uses a schema validation file for the machines which doesn't include GPU_TYPE, but the CROCODILE-CESM/CESM does. The CIME commit for CROCODILE-CESM is 6 months ago while the ESCOMP one is 2 weeks ago.

So the tentative fix for now is just use the CROCODILE-CESM/CESM fork
