Update isaac_panda example for compatibility with Isaac Sim 4.0

[rbabich]

In addition, the header of the Isaac Sim launch script has been updated to indicate that it has been licensed (by NVIDIA) under BSD-3.

Description

Isaac Sim 4.0 will be released soon, and these changes are required for compatibility (while also maintaining compatibility with older versions).

As a bit of housekeeping, I've also received the necessary approvals to release this file under BSD-3. Marq had copied the original version of the file from Isaac Sim, which is licensed under the NVIDIA Omniverse license, hence the "any use [...] without an express license agreement from NVIDIA CORPORATION is strictly prohibited" language in the old header.

@rbabich Do you mind fixing the formatting by running pre-commit (see instructions)?
