Fix release multi-version docs dependencies

[kellyguo11]

Description

Fix the scheduled multi-version documentation job on release/3.0.0-beta2.

The release workflow checks out develop before generating the multi-version site, but it still tried to install docs/requirements.txt. That file was removed from develop when documentation dependencies moved into the root UV test extra, so the job failed before Sphinx started.

Update only the multi-version job to use astral-sh/setup-uv@v6 and uv sync --extra test, matching the dependency setup on develop while leaving release-branch current-doc builds unchanged.

Failed nightly job: https://github.com/isaac-sim/IsaacLab/actions/runs/30600776364/job/91062748798

Type of change

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

Verification

• Confirmed the old command cannot find docs/requirements.txt on the current develop tip.
• Ran uv sync --extra test successfully in a clean checkout of the current develop tip (468 packages resolved and the documentation toolchain installed).
• Temporarily enabled the multi-version job for this pull request and ran it end to end: https://github.com/isaac-sim/IsaacLab/actions/runs/30652411009/job/91228818769
  • Install docs dependencies passed.
  • All selected documentation versions built successfully.
  • Default-version validation and the GitHub Pages artifact upload passed.
  • The job completed successfully in 1h 3m 56s, and deployment remained skipped.
• Reverted the temporary pull-request trigger after the successful run; the aggregate diff contains only the release dependency fix.
• Ran the full repository pre-commit suite before each commit and push; all hooks passed, including YAML validation.

Checklist

• I have read and understood the contribution guidelines.
• I have run the pre-commit checks with the repository formatting command.
• No user-facing documentation update is required for this workflow-only fix.
• The change generates no new static-check warnings.
• I verified the replacement dependency command and the full multi-version job.

Greptile Summary

Fixes the release branch's multi-version documentation dependency setup.

• Replaces setup-python and the removed docs requirements installation with setup-uv.
• Synchronizes the develop checkout's test extra and exposes its virtual environment to later documentation commands.

Confidence Score: 4/5

The PR appears safe to merge, with the non-blocking exception that the new third-party action should be pinned to an immutable commit.

The dependency setup matches the develop-based documentation build flow, but the mutable setup-uv reference permits unexpected upstream changes to affect future workflow runs.

Files Needing Attention: .github/workflows/docs.yaml

Security Review

The new setup-uv action is referenced by a mutable major-version tag, allowing its executed implementation to change without a repository update.

Mutable third-party action reference

astral-sh/setup-uv@v6 allows the executed action implementation to change without a repository update, exposing scheduled and manually dispatched documentation runs to unexpected upstream changes or tag compromise. Pin this action to a reviewed full commit SHA. How this was verified: The new workflow line executes a third-party action through the mutable v6 tag.

Isaac Lab Review Bot

The change updates only the multi-version documentation job so its dependency installation matches the checked-out develop tree, replacing the removed docs/requirements.txt path with the root UV test extra.

• Design and architecture: The checkout target and dependency source are now aligned within the multi-version job. Installing the broader root test extra increases dependency scope, but it uses the dependency definition maintained by develop and leaves release-branch current-doc builds unchanged.
• API: No public Python, extension, or CLI API is affected. The compatibility surface reviewed is limited to the GitHub Actions setup and the existing documentation build commands.
• Implementation: The workflow pins astral-sh/setup-uv by major version, runs uv sync --extra test from the repository root, and adds the resulting root .venv/bin to GITHUB_PATH before invoking make multi-docs from docs. No source package is touched, so no package changelog fragment is needed.

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