GH-5204 fix: invalid Filter.Expression constructor usage in documentation

[LoperLee]

Description

This PR corrects the invalid Filter.Expression constructor usage in the documentation.

The documentation incorrectly illustrated wrapping child expressions in Arrays.asList(). However, the actual Filter.Expression record constructor accepts individual Operand arguments for left and right (binary structure), not a List.

Changes

• Removed the Arrays.asList() wrapper from the Filter.Expression constructor example.
• Updated the example to use the correct positional arguments: new Filter.Expression(type, left, right).
