Note

Low Risk
Single documentation navigation config change; risk is limited to potential sidebar/landing-page routing differences.

Overview
Sets the root for the Web editor docs navigation group to editor/index, and removes editor/index from that group’s pages list so it’s treated as the section landing page rather than a normal entry.
