Remove private index from cuRobo install commands

[yuecideng]

Description

This PR removes the DexForce private package index and trusted-host arguments from the optional cuRobo V2 installation commands. cuRobo is installed directly from NVIDIA's pinned Git source and does not require the Open3DV index.

Dependencies: None.

Issue reference: None.

Type of change

Validation

• black --check --diff --color ./
• git diff --check
• sphinx-build -b html -D autosummary_generate=0 docs/source <temporary-build-dir>

The normal Sphinx build's autosummary generation requires project runtime dependencies such as dexsim that are unavailable in the local environment. With autosummary generation disabled, all 160 documentation pages render successfully; existing project-wide warnings remain.

Checklist

• Black formatting check passes
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works (not applicable: documentation-only change)
• Dependencies have been updated (not applicable)

Greptile Summary

This documentation-only PR removes the DexForce private package index and trusted-host arguments from the optional cuRobo V2 installation commands.

• Keeps cuRobo pinned to NVIDIA’s v0.8.0 Git release.
• Simplifies the CUDA 12.x and CUDA 13.x installation examples.
• Leaves the private index configuration in place for EmbodiChain dependencies that require it.

Confidence Score: 5/5

The PR appears safe to merge because the removed private index is not required by the documented cuRobo installation.

The change only simplifies documentation commands for a package installed from NVIDIA’s pinned Git source, while dependencies requiring the DexForce index remain covered by the separate EmbodiChain installation instructions.
