Fixes#23645
* Added `describedby` attribute to the reference element.
* Eliminated `aria-expanded` attribute to the reference element in order
to conform strictly with WCAG 2.1 rules.
EDIT: The main change of this PR was resolved by #22599. This
complements that PR for some cases without label and complicated layout
to be added.
NOTE: Contributed by @Forgejo.
Added ARIA navigation landmark to navigation bar and aria label for both
nav bar and footer.
