Update MOM6 Overrides to match current MOM6 results

With the merge of mom-ocean/MOM6#1631 into
our MOM6 fork in [MOM6 geos/v3.2](https://github.com/GEOS-ESM/MOM6/releases/tag/geos%2Fv3.2)
without any changes, the answers will change.

So, until these can be tested, we set:
```
USE_HUYNH_STENCIL_BUG = True
EPBL_ANSWER_DATE = 20231231
```

in the `MOM_override` files.
