PR Summary

Low Risk
Routine documentation submodule pointer updates with no impact on production services or security-sensitive logic.

Overview
Automated nightly documentation sync from the scheduled update-nightly workflow.

This PR is expected to bump git submodule references under docs/nightly/ (and related version metadata when new nightly releases are detected) so the hub tracks the latest nightly doc sources. No application or runtime code changes are involved.

Note: the supplied diff contained no file hunks, so specific submodule or version updates could not be enumerated here.
