Update mdcat 0.13.0 -> 0.15.0

Make version restriction for syntect less strict, as mdcat pins it to a
certain version, and we only need it to actually invoke mdcat itself.
So no problem with that lax requirement.

Because mdcat updated its version of pulldown-cmark, we have to update
here as well.

We also had to adapt our error handling, because mdcat chooses to return
a Box<dyn Error>, which is absolutely garbage for us here.
