content: Use ref instead of relref for internal links

Hugo 0.45 changed the behavior of ref and relref. The blog post, docs,
and error messages are all fairly confusing to be honest, but changing
the paths to simply include the document name seems to work, though it
appears there is a non-standard case when resolving a reference from a
post in another language. In that case the only ref syntax that worked
was the longer one that uses "path" and "lang".

Switching from relref to ref is probably unnecessary, but I wanted the
links to be absolute and never really noticed that they weren't.

-These days there isn't much to see of the Greco–Roman city of Pella in northwestern Jordan. Sadly, the ancient ruins here suffer from being slightly smaller, slightly less well-preserved, and slightly less convenient to visit than the similar ruins at [Jerash]({{< relref "posts/greco-roman-ruins-jerash.md" >}}). With a bit of imagination and some historical background, however, they are equally enchanting and even have a unique character of their own.

The walk from downtown to Jabal Ashrafieh is packed with winding streets and steep staircases (some of which go nowhere). To this day the church is one of my favorite landmarks in Amman and I often make the trek there when I'm feeling like getting some exercise and exploring the city. I like to think of it as a pilgrimage — it *is* a religious site after all!
