Small fixes in namelist_cfg

Hi,

I was playing with namelists in the workflow (branch experiment/control-100y-1990-debug-configuration) and I realized that 2 missing/extra points in booleans make f90nml interpret them as strings instead of booleans.

These are the changes needed:

diff --git a/nemo/V40/eORCA1_Z75/1990010100/namelist_cfg b/nemo/V40/eORCA1_Z75/1990010100/namelist_cfg

I'll probably see more of these and probably they are in different branches, I'm not sure about the best way of fixing it.

No rush, just FYI.
