test: Update RTX goldens for the new denoiser default

[nvsekkin]

Description

• Pins CI to the first Isaac Sim build enabling responsive denoising by default.
• Regenerates 20 task and 5 visualizer RTX goldens.
• Updates only affected RGB/RGBA outputs; other AOVs remain unchanged.
• Keeps responsive denoising enabled.
• Marks Kit + Newton tiled pause-frame stability as expected failure under NVBug 6570125 while retaining separate Newton visualizer coverage.

Type of change

• Bug fix (non-breaking change which fixes an issue)

Isaac Lab Review Bot

The PR updates the pinned Isaac Sim CI image digest for the DLSS-RR denoiser-default change and refreshes the corresponding RTX and Kit rendering goldens, with test-only changelog fragments for both affected packages.

• Design and architecture: The change remains limited to shared CI image configuration and rendering test fixtures. The pin is documented with the motivating Kit revision and issue, preserving traceability between the runtime change and regenerated baselines.
• API: No public APIs, CLI arguments, configuration schemas, exports, or documented user behavior change. The required per-package changelog handling is satisfied with .skip fragments appropriate for test-only changes.
• Implementation: The patch updates 20 task golden LFS pointers and five visualizer captures. The task updates are confined to RGB/RGBA RTX-renderer baselines, including the registered cartpole task’s default-renderer variants, while unrelated AOV and simple-shading fixtures remain untouched. Binary image contents cannot be assessed from the textual patch, so final confidence still depends on the rendering test results and provenance of the regenerated captures.

No blocking issues. No inline issue met the actionable-evidence threshold; the assessment above records the review feedback.

Automated review; human maintainers own approval decisions.

Greptile Summary

Pins CI to the Isaac Sim build that enables responsive denoising by default and aligns the affected rendering baselines with that build.

• Regenerates affected RTX RGB/RGBA task and visualizer goldens.
• Separates Newton tiled visualizer coverage by visualizer kind.
• Marks the known Kit pause-frame instability as an expected failure while retaining Newton visualizer coverage.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

.github/workflows/config.yaml	Pins the Isaac Sim CI image to the responsive-denoising build used to generate the updated rendering baselines.
source/isaaclab_visualizers/test/test_visualizer_integration_newton.py	Parameterizes tiled visualizer testing so only the known Kit stability case is expected to fail while Newton remains independently covered.
source/isaaclab_tasks/test/golden_images	Updates the affected task RTX RGB and RGBA golden-image pointers for the newly pinned renderer behavior.
source/isaaclab_visualizers/test/golden_images	Regenerates five visualizer rendering baselines against the pinned Isaac Sim build.
