[release/public-v2.1.0] Plotting script fix: correct a variable name to a lower-case

[natalie-perlin]

NB: Correction similar to a PR-468 for a develop branch

DESCRIPTION OF CHANGES:

Running plotting script throws an error when new miniconda/python are used.
The fix is to use the lower-case name of the one of the plotted variables.

The fix originally found and applied by @EdwardSnyder-NOAA , tested by
@BruceKropp-Raytheon . The fix was limited to applying it using "sed" at the time of plotting.

Type of change

• Bug fix (non-breaking change which fixes an issue)

• hera.intel
• orion.intel

Looks good to me!

The following was added by Bruce Kropp in the Jenkins configuration file on all platforms:

sed -i 's/Geopotential Height/Geopotential height/g' ./ush/Python/plot_allvars.py

This is done so the plotting script can run via Jenkins. It'll fail because the height in GH is now lower case. It sounds like there was a change in how the NetCDF file displays GH and the proper changes didn't make into the plotting script.

This update corrects the inconsistency in Geopotential height for plot_allvars.py, so approving this PR.
