- Add headings to examples section
- Clarify styles and customization options in examples
- Add dismiss buttons to all toasts
- Missing period added for consistency
- Update roles, tweak text

Also remove close button everywhere just let it when autohide is set to false

Add `tabindex="-1"` and `aria-disabled="true"` to disabled link

* Tweak the accessibility/reduced motion text

include mention of carousel slides, remove the (now inaccurate, as Firefox 63 includes it too) mention that support is limited to Safari/macOS

xref https://github.com/twbs/bootstrap/issues/27525

* Add new callout for reduced motion

* Add variable to control prefers-reduced-motion media query support

* Add callout about prefers-reduced-motion to all components currently using animation which are affected

- Remove `.sr-only` span for previous/next page, there is already`aria-label`
- Add `aria-disabled="true"` and `aria-current="page"`

Now that we don't have the ToC issue with the examples' headers in ToC, we can safely do this.no_toc_section_class

Instead of using an external source since this is only a one time note it is safe to be placed within the document itself.

In the event that the content is larger than the image, the content will continue to be displayed outside the image itself. There are some workarounds but they apply only to browsers that support this option and IE11 is not one of them.

* refine deprecated holder.js color syntax
  * remove `#55595c:#373a3c`
* harmonize with all other holder.js examples
