fix(a11y): add aria-label to navigation drawer collapse button (WCAG … (#23287)

…4.1.2)
Fixes #23131

Added `aria-label` to the navigation drawer collapse/expand button 
(LightIconButton with IconLayoutSidebarLeftCollapse/RightCollapse), 
which previously had no accessible name for screen readers.

Verified with axe DevTools scan on localhost — the button-name 
violation for this element no longer appears.
