Snow depth variable descriptors are incorrect in GFS_surface_composites*meta

[ClaraDraper-NOAA]

Description

In GFS_surface_composites_post.meta and GFS_surface_composites_pre.meta the standard name and long name of snowd (and snowd_lnd and snowd_ice) are incorrect.

snowd is the physical snow depth (compare to weasd which is the liquid equivalent snow depth = amount of water in the snow pack)

Both files have:

[snowd]
standard_name = lwe_surface_snow
long_name = water equivalent snow depth

which should be just "snow depth" with no "water equivalent"

Also, the weasd standard name given as:
lwe_thickness_of_surface_snow_amount which is probably correct if lwe stands for "liquid water equivalent"

The weasd_lnd standard_name is water_equivalent_accumulated_snow_depth_over_land which is a better descriptor.

Steps to Reproduce

This is a documentation fix only.
