Bug description

Currently, Gluten translates json_tuple(a, key) directly into get_json_object(a, key). This causes issues when the key contains a dot (.), leading to incorrect parsing behavior.

Details:
For example, if a = '{"a.b":"a"}', then:

json_tuple(a, 'a.b') correctly returns "a"

But the translated expression get_json_object(a, '$.a.b') treats the key as a nested path, looking for a field b under a, which results in null
