This PR updates the parm/config/gfs/config.resources and env/WCOSS2.env
files for the BUFR sounding job "postsnd." It includes adjustments to
resource settings such as tasks per node and memory allocations for
various GFS resolutions, including C768, C1152, and others.

Here are the proposed changes:

C768: 7 nodes, 21 tasks per node
C1152: 16 nodes, 9 tasks per node
