Fixes missing visible attribute in spawn_ground_plane (isaac-sim#3304)

# Description

`GroundPlaneCfg` allows for specifying `visible` parameter, but this
would not being parsed in `spawn_ground_plane`, resulting in the
parameter being a no-op when specified. This change adds a fix to parse
the `visible` parameter from the cfg and sets the visibility attribute
for the ground plane cfg appropriately.

Fixes isaac-sim#3263
