Remove unused pagination link

[sowasred2012]

Done

Removed .p-article-pagination__link, as it wasn't being used anywhere (its variants are).

Fixes #4025

QA

• Make sure tests pass, the class wasn't used so it shouldn't impact anything.

Check if PR is ready for release

• PR should have one of the following labels to automatically categorise it in release notes:
  • Feature 🎁, Breaking Change 💣, Bug 🐛, Documentation 📝, Maintenance 🔨.

LGTM,

Even thought it's not used anywhere maybe worth adding to upgrade guide that it was removed? So if anyone searches for it they'd know.
