[test](case) Fix instability case caused by fold_constant_by_be. (#51445)
Known issue: float outputs differ between backend and frontend.
For example, 2.0 prints as “2” on be but “2.0” on fe.
```mysql
mysql> set enable_fold_constant_by_be = true;
mysql> select dict_get_many("test_dict_get_many.multi_key_dict",
["k2","k3"], struct(2,'ABC'));
+----------------------------------------------------------------------------------+
| dict_get_many("test_dict_get_many.multi_key_dict", ["k2","k3"],
struct(2,'ABC')) |
+----------------------------------------------------------------------------------+
| {"k2":2.0, "k3":"DEF"}
|
+----------------------------------------------------------------------------------+
mysql> set enable_fold_constant_by_be = false;
mysql> select dict_get_many("test_dict_get_many.multi_key_dict",
["k2","k3"], struct(2,'ABC'));
+----------------------------------------------------------------------------------+
| dict_get_many("test_dict_get_many.multi_key_dict", ["k2","k3"],
struct(2,'ABC')) |
+----------------------------------------------------------------------------------+
| {"k2":2, "k3":"DEF"}
|
+----------------------------------------------------------------------------------+
