New Dart tests are failing

### Brief summary of bug

These two tests, which were brought in with #398 are failing.

FAIL ERI.ne3pg3_ne3pg3_t232.BHISTC_LT_DART.derecho_intel.allactive-DART_lowres CREATE_NEWCASE
FAIL MCC.ne3pg3_ne3pg3_t232.BHISTC_LT_DART.derecho_intel.allactive-DART_lowres_components-mom-cime_config-testdefs-testmods_dirs-mom-tx10deg CREATE_NEWCASE

### General bug information

**CESM version you are using:** cesm3_0_beta09

**Machine you are using:** derecho

**Have you modified the code? (If so, please point us to you changes.):** No

### Details of bug

The 2 new Dart tests are misconfiguration. Since this is a fully couple tests the resolution should be ne3pg3_t232. A new grid alias will be need to be added. The testmod is broken, the testmod should be allactive/DART_BHIST_lowres--mom/tx10deg.

I've tested with these changes and the ERI test passed.

### Steps to reproduce the problem. Include externals description file(s) and link to public repository

Run create_test with the above tests names.

### Screen output or log file showing the error message and context

@kdraeder I wanted to give you a heads up that these 2 tests failed during the prebeta testing. I plan on having a fix for alpha10a when it's made.
