Add role="dialog" in modals via JavaScript

Restore word-break: break-word on .text-break to fix text breaking on flex containers

Update to `@rollup/plugin-babel`

Allows use of background-color and more. Fixes #29033 for v5.

For some reason, custom checks in CSS columns need a new stacking order to maintain visibility. This PR adds `z-index: 1` to trigger that new stacking order.

Fixes #29607

Remove moot fail-fast option

* remove favicons meta tags
* copy the two brand images we use in the examples
* copy dist and brand images into an assets folder

While it might not be possible to invalidate the cache by changing test.yml, this should speed things up a lot due to `bundle i` taking most of the time.

This partially reverts commit 6c464938.
