ERP tests no longer support the "month" length option

[ekluzek]

Brief summary of bug

From @fischer-ncar

Hi Erik,

Jim made some changes to the testing scripts which caused ERP tests to not support _Lm anymore. This is a low priority, but when you get the time, can you change

ERP_P64x2_Lm36.f10_f10_mg37.I2000Clm50BgcCrop.derecho_intel.clm-clm50cropIrrigMonth_interp
to
ERP_P64x2_Ly3.f10_f10_mg37.I2000Clm50BgcCrop.derecho_intel.clm-clm50cropIrrigMonth_interp

Thanks
Chris

I'm seeing this on Izumi as well with the submodule update PR (#2853). It does apply to just the use of "month" for the length option for other ER tests for example the ERS test shows

 ---------------------------------------------------
2024-11-14 14:54:46: ERROR: stop_option nmonths not available for this test
 --
```-------------------------------------------------

So other izumi tests that fail in #2853:

ERS_Lm13.f10_f10_mg37.I1850Clm60Bgc.izumi_intel.clm-monthly_matrixcn_fast_spinup        (NLCOMP RUN)
