Updates version to release 2.1.1 (#3047)

# Description

A long overdue release of IsaacLab. Since we will soon have IsaacLab 2.2
out which primarily supports IsaacSim 5.0, this release marks a "stable"
checkpoint of IsaacLab that works with IsaacSim 4.5.

We are working towards improving our release cycles to have more
frequent patch releases.
