[Pagination] Fixes in a11y tab images

[alina-jacob]

Acceptance criteria

Some of the images in the a11y tab of Pagination are incorrect and need fixing.

1. Labeling section: Update the Select component's tooltip to read as "Page number" instead of "Page number, of 40 pages"
   

2. Tab stops will help navigate through the icon-only buttons. The "ellipse" which is a Select component, can be opened using space and arrow keys, navigated using arrow keys, selected using space and enter keys. Reflect this information in the image.
   

3. Space and Enter selects, update the image reflecting the same.
