Increased the No. of default levels to 40

[AminIlia-NOAA]

Description

GFSv17 and GEFSv13 require 40 levels for 3D variables for operational forecast . The default levels in case user doesn't define number of levels was 12 in the shell. I suggest to increase the levels to 40 as modified in this shell code (line238).

Resolves #1234

Apologies. The script is used. I thought I was looking at the gfs-utils.
One note, on the levels, for mx500, the number of levels are 25. Changing to 40 will cause a failure when generating ocean products at mx500 resolution. I believe that is why the default number of levels were capped at 12.
The operational system will use 40 levels, as prescribed by the yaml configuration here
