fix(activedescendant): rollback scroll logic to use scrollTop

[saiponnada]

Rolled back changes to previous state #175

Context

• scrollIntoView is causing further issues with dependency libraries like floating-ui. Hence rolling back the changes to use previous implementation using scrollTo instead.
• Previously this change was made because of the makeup listbox options not being focused when using kb with a long list whereas this was never an issue on ebayui-core.

Changes

• Roll back changes to use scrollTo instead
• Updated Listbox code to pass parentElement as container to active-descendant
