Note

Low Risk
Low risk documentation navigation change: it only removes a redundant sidebar entry pointing to the same storage-buckets page, with no code or content logic impact.

Overview
Removes a duplicate storage-buckets child item (“Buckets vs Git Repositories”) from docs/hub/_toctree.yml to avoid listing the same page twice under Storage Buckets.

The section now links directly to the relevant content via the parent storage-buckets page and the remaining storage-buckets-security subpage.
