CSW / GetRecords / Number of matches in page info

[fxprunayre]

Follow up of #7599

result.hits().hits().size() returns number of records in response, not total hits matching search. numberOfRecordsMatched is wrong.

  <csw:SearchResults numberOfRecordsMatched="10" numbe

Tested, works fine.

In 4.2.x and works fine:

core-geonetwork/csw-server/src/main/java/org/fao/geonet/kernel/csw/services/getrecords/SearchController.java

Line 469 in 0c9bc11

long numMatches = result.getHits().getTotalHits().value;

So probably this is a regression related to the upgrade to Elasticsearch 8.
