Olivero: The styling of the pager is not matching the design.

Problem/Motivation

I was reviewing the design and I observed that the styling of the pager is different from the design. In the design, there is a border defined on the items but in the current implementation, the styling is different. See the attached screenshot for reference.

Steps to reproduce

1. Set up the Drupal site, and moved on Olivero theme.
2. Add some content (Create articles and a basic page)
3. See the pager styling (match with the design)

Proposed resolution

Need to style as per the design

Remaining tasks

User interface changes

API changes

Data model changes
