Correct region name to ISMIP6 Greenland Regions

[mark-petersen]

Region group name in files_for_e3sm diagnostic masks did not match geometric features. After correcting, this works for IcoswISC240.

@mark-petersen, can you describe in more detail the test you ran (which machine, which compilers, etc.)?

I'll merge as soon as CI passes and this more detailed description gets added.

This update was missed in #874 when geometric_features was updated to v1.6.0.

The fix looks right to me!

Tested on chicoma by running

 220: ocean/global_ocean/IcoswISC240/mesh
 221: ocean/global_ocean/IcoswISC240/WOA23/init
 229: ocean/global_ocean/IcoswISC240/WOA23/dynamic_adjustment
 230: ocean/global_ocean/IcoswISC240/WOA23/files_for_e3sm
compass setup -n 220 221 229 230 -p $e/master/components/mpas-ocean -w $r/251217_test_files_for_e3sm

I was able to compass run within files_for_e3sm/diagnostic_masks and it ran all the way through and produced the expected files. Before this fix it ends with an error

Thanks @mark-petersen for discovering the issue and fixing it!
