Add missing h_neglect

[NoraLoose]

Looks like the addition of h_neglect is missing in one line for the computation of zonal isopycnal slopes.

Note that is is correctly added in the meridional counterpart:

MOM6/src/core/MOM_isopycnal_slopes.F90

Lines 363 to 370 in 399a7db

	hg2A = h(i,j,k-1)*h(i,j+1,k-1) + h_neglect2
	hg2B = h(i,j,k)*h(i,j+1,k) + h_neglect2
	hg2L = h(i,j,k-1)*h(i,j,k) + h_neglect2
	hg2R = h(i,j+1,k-1)*h(i,j+1,k) + h_neglect2
	haA = 0.5*(h(i,j,k-1) + h(i,j+1,k-1)) + h_neglect
	haB = 0.5*(h(i,j,k) + h(i,j+1,k)) + h_neglect
	haL = 0.5*(h(i,j,k-1) + h(i,j,k)) + h_neglect
	haR = 0.5*(h(i,j+1,k-1) + h(i,j+1,k)) + h_neglect

Hi Nora, could you re-send this to the NOAA-GFDL/MOM6 repository for review? Thanks
