Outbound federation fixed

Hey everyone, sorry for the bit of issues with the outbound federation.

We recently updated the site to 0.19.18 and that ended up breaking the outbound federation for a bit. Luckily no activity silently failed so all posts/comments/etc. were able to be retroactively sent to other instances so that everything made during the downtime is still federated as normal now.

A couple larger instances might still be behind on content for a bit as they catch up on activities but if this post can be seen in another instance that means that instance is fully caught up. (should only be lemmy.world and a couple others that are behind)
