Bundled themes: the tag cloud widget should output a list

Splitting this out from #35566
Bundled themes should show best practices to theme authors. About the Tag Cloud widget, the latest patch on #35566 proposes some accessibility improvements, however it doesn't force the tags to be output as an unordered list to avoid the need to output some inline stylesheet.
A better option would be using the format argument to tweak the output on a case by case basis.
From a semantic perspective, the tags list is... well, a list. Setting the format argument to list would allow assistive technologies to announce the list as a list and the number of items in the list. Most of the users from the a11y testers group expressed a preference to have the number of items being announced, see the test results on #35566.
This would require some simple CSS adjustments, which is trivial to do in the Themes stylesheet.
