JSON_SCHEMA_VALID: multipleOf must be greater than zero

multipleOf

The value of "multipleOf" MUST be a number, strictly greater than 0.

https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.6.2.1

Case:

SET @schema = '{

                  "multipleOf": 0

                }';

SELECT JSON_SCHEMA_VALID(@schema, '2');

Expected that there will be a warning, but actual result is:

JSON_SCHEMA_VALID(@schema, '2')

0

Also maybe a value like 0.1("multipleOf": 0.1) needs to be checked but I'm not sure
