Replace hard-coded query in gathering/db/wikidata/standardizing by the one in https://github.com/lotusnprod/lotus-sparql-examples

```sparql
SELECT DISTINCT ?name (COUNT(DISTINCT ?id) AS ?count) WHERE {
  ?id wdt:P31 wd:Q16521;
    wdt:P105 wd:Q34740;
    wdt:P225 ?name.
}
GROUP BY ?name
HAVING ((COUNT(?id)) > 1 )
ORDER BY DESC (?count)
```
