Add pagination on repo pipelines view

Clear and concise description of the problem

It is not possible to see list of older pipelines for a repo

Suggested solution

Add pagination on https://ci.woodpecker-ci.org/repos/3780

Alternative

Add a load more button. Although, I prefer pagination, because then you can share a link to the page and you will see the same view.
