Rucha Deodhar 7321c71aa1 MDEV-31032: UBSAN|downcast of address X which does not point to an ...

object of type 'Item_string' in sql/json_schema.cc

Analysis: make_string_literal() returns pointer of type
Item_basic_constant which is converted to pointer of type Item_string. Now,
Item_string is base class of Item_basic_constant, so the error about
downcasting.
Fix: using constructor of Item_string type directly instead of
downcasting would be more appropriate.
