ScrollBar (at_bottom, at_top)

[JaskRendix]

PR refactors the ScrollBar widget.

• introduced _update_slider_position_flags() to manage the _at_bottom and _at_top flags, ensuring they reflect the slider's position
• created _update_slider_rect() to centralize the logic for updating the slider's rectangle, reducing code duplication
• created _set_slider_position() to set the slider's position, update the rectangle, update the flags, and render, making it easier to manage slider changes
• added is_at_bottom() and is_at_top() to provide ways to check the slider's position
• implemented bump_to_top() and bump_to_bottom() for easy movement to the slider's extreme positions
• extracted mouse event handling into _handle_mouse_event() and touch event handling into _handle_touch_event(), making the update() method less cluttered
• extracted the render shadow code into _render_shadow()
• added new unittest

could you add it to the pygame-menu-ce?

Hi @JaskRendix . Do you think you will add future changes? to wait them for publishing the new v4.5.2

[JaskRendix]

@ppizarror the main ones were bottom_to_top and top_to_bottom, so no need to hurry

@JaskRendix. Today I just updated https://pypi.org/project/pygame-menu-ce/ to the latest version. Let me know if you have any issues. Greetings!
