fix(route/wikipedia): parse current events top/bottom template form (#23122)

Browse Source 
The daily pages used to pass the items as the `content=` argument of a single
{{Current events}} call; they now sit between a top=yes and a bottom=yes call.

The parser only matched the old form, so it returned null for every day and
the route failed with "this route is empty". Match the top/bottom pair.
