chore(lib): update Pagination

- In `src/components/pagination/PaginationButton.vue`,
    - The `disabled` attribute of the button is replaced with
      `disabledOrUndefined`. On Vue 3, setting a boolean attribute
      `false` does not remove it. To do so, `null` or `undefined` has
      to be returned. `disabledOrUndefined` deals with new behavior.
- Common,
    - Automatic ESLint fix is applied.
