Reduce maximum result size of XWiki search_pages

This is only done to improve worst-case latency, because
we perform one additional request per result.

Local testing showed a latency above 1000ms for 50 results
and ~500ms for 20 results. I'd expect real world scenarios to
be slightly worse, because of higher network latency.
