[Bug]: unslick is missing in filterSettings

[rjsdnql123]

The unslick property is missing in the filterSettings, so the value of unslick inside InnerSlider is always undefined

Upon reviewing the code for the pull request submitted earlier, I found an issue indicating a bug. Upon examining the code, I discovered that the unslick property was missing in the filterSettings function, resulting in the unslick property inside InnerSlider being undefined. I have fixed this issue.

This bug appears to manifest as the slider buttons being visible despite all elements being displayed within the slider.

before

1. element 9

const settings = {
    dots: true,
    infinite: false,
    speed: 500,
    slidesToShow: 10,
    slidesToScroll: 3
  };

after

---

The problematic code only returns undefined, so the arrow will always be rendered.

@akiran Without unslick, the expected behavior is not occurring. Could you please confirm this?
