Added new components to enhance the navigation drawer's edit mode functionality. The WorkspaceSectionAddMenuItemButton allows users to add new items directly, while the WorkspaceSectionListEditModeFallback provides a fallback UI for when the navigation menu is in edit mode, integrating read-only item lists and the add button. Updated NavigationDrawerSectionForWorkspaceItems to utilize the new fallback component.
