Error in activity reporter not visible, need to scroll to the top

Add a scrollIntoView method for the vcd-banner-activity-reporter. This increases the visibility of success and error messages by scrolling the activity reporter banner into view.

Testing Done:
- Added examples to have a page where activity banner is not visible so the scrollIntoView method is used.
- Observed that the scrolling to the activity banner was successful.
