Migrate from laminas-paginator to pagerfanta

[acelaya]

Laminas-paginator has some hard-to-solve dependencies that are blocking it from adding support to PHP 8.

Pagerfanta has very similar features and exposes a very similar API. It's a bit smaller and it's a bit more optimized internally. It also supports PHP 8 already, so it's a good candidate to replace laminas-paginator.
