Description
Problem
Section-folding affects only the chapters and sub-chapters. It doesn't allow collapsing or folding the page headers creating by the sidebar-header-nav (#2822).
Proposed Solution
Add a new option like output.html.fold.headers = true to enable collapsing the headers.

Research direction
Start by locating the implementation of sidebar-header-nav and comparing it with the existing output.html.fold section-folding behavior. Read the linked mdBook renderer configuration documentation and determine how a new output.html.fold.headers option should be exposed. Done means page headers can be collapsed when enabled without changing the existing chapter-folding behavior.
