Disallowed markup in definition lists

MR changes two templates to use divs instead of definition lists, and uses aria-details to associate the label and description now that it isn't automatically associated via html tag.

Hi,

Tested the MR !273 to address the issue error appears with a basic A11y scan. Now it's works fine after '<dl><dd><dt> to <div>' tags change in MR.

Testing Steps:
1. Install the Drupal 10.0.x version and enable gin 8.x.
2. switch to MR and verified the changes.

Looks Good for RTBC
