Test-type categorization of the ORCA2_ICE_OBS SETTE test

Context and analysis

The SETTE reproducibility test of the ORCA2_ICE_OBS configuration is carried out as part of the SETTE restartability and not as part of the SETTE reproducibility tests in the current NEMO main and branch_4.2 versions.

Fix

The SETTE test-type category of the ORCA2_ICE_OBS configuration could be changed with the modification
