12bee54cf7 [fix](Nereids) function implict cast for json is not work well (#24852) 
for sql like:

SELECT JSONB_EXTRACT('{"k1":"v31","k2":300}','$.k1');

the result should be

+------------------------------------------------+
| jsonb_extract('{"k1":"v31","k2":300}', '$.k1') |
+------------------------------------------------+
| "v31"                                          |
+------------------------------------------------+

but curent result is

+------------------------------------------------+
| jsonb_extract('{"k1":"v31","k2":300}', '$.k1') |
+------------------------------------------------+
| <null>                                         |
