JSON_SCHEMA_VALID rejects duplicate array elements when uniqueItems is false

Description

JSON Schema Draft 2020-12 says an instance validates successfully when uniqueItems is false, regardless of whether the array contains duplicates. MariaDB returns false for a valid instance.

How to repeat

SELECT VERSION();

SELECT JSON_SCHEMA_VALID('

', '[1,1]') AS duplicate_items;
SELECT JSON_SCHEMA_VALID('{}', '[1,1]') AS omitted_keyword_control;
SELECT JSON_SCHEMA_VALID('

', '[1,1]') AS true_keyword_control;

Actual result

MariaDB returns 0, 1, 0.

Expected result

The results should be 1, 1, 0. Duplicate strings and duplicate objects are also incorrectly rejected with uniqueItems:false.
