Fixes error in hdf5 loading and hides simulation settings window (#246)

# Description

This change enforces the Isaac Lab extensions to be loaded last to avoid
conflicts in hdf5 with omniverse extensions. Additionally, we hide the
Simulation Settings window by default in `SimulationContext` as
specifying it in the app file does not seem to work. Also adds the
IsaacLab folder to python path for benchmarking scripts.
