Greptile Summary

This PR removes explicit version constraints for the URDF importer extension to support Isaac Sim 6.0. The changes enable dynamic version resolution by replacing isaacsim.asset.importer.urdf-2.4.36 with isaacsim.asset.importer.urdf across configuration files, source code, and tests.

Key Changes:

• Removed {version = "2.4.36", exact = true} constraint from apps/isaaclab.python.kit and apps/isaacsim_5/isaaclab.python.kit
• Updated urdf_converter.py:50-51 to use version-agnostic extension name for enabling and checking extension status
• Updated test files to use the new extension naming convention
• Switched XR extension from omni.kit.xr.profile.ar to omni.kit.xr.bundle.generic for Isaac Sim 6.0 Teleop compatibility
• Added CHANGELOG entry documenting this fix in version 0.50.6

The changes are consistent and complete across all affected files. All references to the versioned extension name have been properly updated.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward version constraint removals that enable Isaac Sim 6.0 compatibility. All references to the versioned extension name have been consistently updated across configuration files, source code, and tests. The modifications follow a clear pattern: removing explicit version constraints to allow dynamic resolution of the URDF importer extension bundled with Isaac Sim 6.0. No logic changes or new functionality was introduced.
• No files require special attention

let's keep this for the 5.X app files since we want to use this exact version for 5.1

This app doesn't work for 5.0: #4384

[Mayankm96]

We should probably do version specific app files (for 5.0) as well?
