Updates documentation for spark installation

[kellyguo11]

Description

imgui doesn't provide prebuilt packages for ARM, so we need to install additional libraries to build it during installation.

Also updates some outdated links in docs.

Greptile Summary

This PR updates documentation for ARM (aarch64) installation requirements and upgrades PyTorch dependencies. The key changes include documenting that imgui-bundle must be compiled from source on aarch64 platforms (like DGX Spark) due to missing pre-built wheels, requiring OpenGL and X11 development packages. PyTorch is updated from 2.9.0 to 2.10.0 across all installation documentation and setup files. Additionally, fixes a missing warp import in tiled_camera.py that would cause runtime errors, updates Newton documentation URLs to include /latest/ path segment, and improves internal documentation links.

• Fixed missing import warp as wp in tiled_camera.py (would cause NameError when calling reset() or _update_buffers_impl())
• Added comprehensive aarch64 installation notes explaining imgui-bundle build requirements
• Updated PyTorch/torchvision to 2.10.0/0.25.0 consistently across all setup files and documentation
• Changed window title from "Isaac Sim" to "Isaac Lab" for proper branding
• Updated Newton documentation URLs and migration guide links

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• All changes are straightforward: documentation updates, consistent version bumps, and a simple bug fix. The warp import fix resolves a real issue that would cause runtime errors. PyTorch version updates are consistently applied across all files. No complex logic changes or risky operations.
• No files require special attention
