feat(query): remove cutoff_frequency (#134)

 remove cutoff_frequency, deprecated in es7.3.0, forbidden in es8

From https://www.elastic.co/guide/en/elasticsearch/reference/8.8/migrating-8.0.html

    The cutoff_frequency parameter has been removed from the match and
    multi_match query.

    Details
    The cutoff_frequency parameter, deprecated in 7.x, has been removed
    in 8.0 from match and multi_match queries. The same functionality
    can be achieved without any configuration provided that the total
    number of hits is not tracked.

    Impact
    Discontinue use of the cutoff_frequency parameter. Search requests
    containing this parameter in a match or multi_match query will
    return an error.

Note in the above "...provided that the total number of hits is not
tracked".

`track_total_hits` does not appear in the pelias codebases, so we
shouldn't have any issues there.
