Updates {@link #translations()} to use name translations fetched from wikidata based on the
<a href="https://www.wikidata.org/wiki/Wikidata:OpenStreetMap">wikidata tag</a> on OSM elements.
<p>
When either {@code only_fetch_wikidata} or {@code fetch_wikidata} arguments are set to true, this downloads
translations for every OSM element that the profile cares about and stores them to {@code defaultWikidataCache} (or
the value of the {@code wikidata_cache} argument) before processing any sources.
<p>
As long as {@code use_wikidata} is not set to false, then previously-downloaded wikidata translations will be
loaded from the cache file, so you can run with {@code fetch_wikidata=true} once, then without it each subsequent
run to only download translations once.

@param defaultWikidataCache Path to store downloaded wikidata name translations to, and to read them from on
                            subsequent runs. Overridden by {@code wikidata_cache} argument value.
@return this runner for chaining
