(bug 56018) add descriptions to entity search

https://gerrit.wikimedia.org/r/91303

CirrusSearch (and likely the old search) considers size of the search text when ranking search results.

This means that if we just put labels and aliases in search text. most items are similar. (although more translations help)

If we put site links and descriptions in, that will help a bit more with ranking when it comes to item size, and also searching for particular words or phrases that only appear in descriptions or site links.

claims could also by "textified" and put into the search text for full text searching.
