[9.20] fix: usr: Log dropped or slipped responses in the query-errors category

Browse source 
Responses which were dropped or slipped because of RRL (Response Rate
Limiting) were logged in the ``rate-limit`` category instead of the
``query-errors`` category, as documented in ARM. This has been fixed.

Closes #5388

Backport of MR !10676

Merge branch 'backport-5388-rrl-log-category-fix-9.20' into 'bind-9.20'

See merge request isc-projects/bind9!10725
