Fix task-list checkbox styling (#10668)

* Fix task-list checkbox styling

The pandoc renderer will append the class "task-list" to the ul element
wrapping a li with one or more check-boxes. This allows us to select for
them, removing their list-style-type property. However, goldmark and the
gfm spec doesn't specify the "task-list" class name, so we can't use
that to fix the issue there.

* Update to goldmark v1.1.25

This version adds the missing space after a checkbox.

Resolves: #9656
