Fix off-by-one error in parameter count validation for scriptlets without parameters in no-invalid-scriptlets rule

- Changed condition from `parameterIndex > 1` to `parameterIndex > 0` when checking for extra parameters
- Ensures scriptlets with no defined parameters correctly reject any parameters beyond scriptlet name
- Fixes duplicate error reporting where first parameter was incorrectly validated twice
- Updated documentation example to show correct single error for missing 'property' parameter
