Lack of padding on pagination buttons

Overview of the problem

Oruga version: [0.1.4]
Vuejs version: [2.6.11]
OS/Browser: Ubuntu 20.04/Firefox

Description

The pagination buttons have a min-width but no padding. This makes links that have big numbers or even the previous and next buttons get a bit weird with the text next to the border:

I was thinking on adding a --oruga-pagination-link-padding variable and set it to the same value of --oruga-button-padding at first. This would leave things this way:

Notice that the buttons are not always squared anymore once you get to two digits, but I guess this is fine, its what I would expect.
