Add missing v4 docs for tooltip/popover methods

Generate correct breakpoints for navbar-toggleable-* and generate toggleable without media query to never collapse

The example code has the class `"modal fade"`, but the visible example has the class `"modal"`. `"fade"` appears to not work for modals that you do not intend to animate onto the page

Fix Modal documentation about _handleUpdate method + move to public scope

Fix accordion behavior with JQuery interface

fix data-pause documentation for carousel

Carousel - Add attributes from and to for Slid and Slide events

- Justified and fill nav variants need .nav-item classes on the anchors in addition to .nav-link
- Fix broken styles for the .nav-justified class which wasn't actually doing what we needed it to

- revert back to display block for list items to prevent unwanted behaviors
- fixes a handful of other linked issues (see main thread)
- updates docs to include more utilities for the one example

— Rename display docs page
— Move print display utils to display utils page
— Drop remaining of responsive utils page as it's being replaced with display utils
— Update nav to reflect changes
