Subject: [PATCH] Twenty Thirteen, Twenty Sixteen: Use default display for
 summary element.

Within the details block, style the `summary` element using the default display, `list-item`, this ensures the toggle icon appears indicating the summary can be expanded or contracted.

Props ankit-k-gupta, nicolefurlan, poena, sabernhardt.
Fixes #58915.
