CTSM Issues Fixed (include github issue #):
Resolves #1895

Are answers expected to change (and if so in what way)?
Yes, because Clm6 tests that do not specify the datm input will now get CRUJRA2024 instead of GSWP3v1.

Any User Interface Changes (namelist or namelist defaults changes)?
Adding Crujra to compset names.
Adding 2 new tests that explicitly include Crujra in their compset names.
All Clm60 tests that do not include a datm option in their compset will now default to Crujra.

Does this create a need to change or add documentation? Did you do so?
It does, and I did not, yet.

Testing performed, if any:
See relevant posts below.

First attempt at testing:
./create_test ERP_P128x2_Ld30.f45_f45_mg37.I2000Clm60FatesSpCrujraRsGs.derecho_intel.clm-FatesColdSatPhen

Second set of tests on derecho:

OK make black & lint (the latter gives two warnings)
PASS python
PASS ./build-namelist_test.pl
OK ./run_sys_tests -s aux_clm -c ctsm5.3.021 --skip-generate
OK? ./run_sys_tests -s aux_cdeps -c /glade/campaign/cesm/cesmdata/cseg/cesm_baselines/cdeps1.0.55 --skip-generate

Checked the last two suites with these commands:

./cs.status.fails | grep -v PASS | grep -v NLCOM | grep -v '21: DIF'
./cs.status.fails | grep -v NLCOMP

In aux_cdeps, this test fails here but also in vanilla ctsm5.3.021:

SMS_D_Ld3.f10_f10_ais8gris4_mg37.DATAMODELTEST.derecho_gnu
ERROR: Invalid compset name, DATAMODELTEST, all stub components generated

3rd round to test the "clm5" changes

PASS ./build-namelist_test.pl
PASS ./create_test ERP_P128x2_Ld30.f45_f45_mg37.I1850Clm50BgcCropCrujra.derecho_intel.clm-default
