@ng-bootstrap/ng-bootstrap 16.0.0 on Node.js NPM

This release bumps minimum required versions to Angular 17.0.0 and Bootstrap 5.3.2.

Main features:

dark mode support for all components and demo site.
new stacked progressbar markup in Bootstrap 5.3 allowed us to do the long-standing stacked progressbar feature request.
Ethiopian calendar for datepicker.
old component-based accordion implementation is removed (it was deprecated in 14.1.0 in favor of directive-based implementation).
we're using new control flow syntax internally and for all demos.

dropdown: remove deprecated NgbNavbar directive (c2c8061)

minimum required versions are now Angular 17.0.0, Bootstrap 5.3.2 and Popper 2.11.8
accordion: removed component-based accordion. It was deprecated in 14.1.0
accordion: removed type property from the NgbAccordionConfig. It was deprecated in 14.1.0.
we use inject function internally more than before, so constructor signatures have changed for all components. If you extend our components (and you really shouldn't do it), you might need to update your code.
nav: NgbNavbar directive is removed, as it is no longer required. It was deprecated in 14.2.0.
nav: default value for the @Input() keyboard: boolean | 'changeWithArrows' was changed from false to true, meaning that all navs are now keyboard accessible by default and focus between navs moves with arrow keys. Focusing behavior follows the WAI-ARIA tab recommendation as well as Bootstrap's nav implementation. To turn off keyboard support set keyboard to false either on the individual NgbNav or via NgbNavConfig
