Docx Reader: Remove DummyListItem type

Change 5527465c introduced a `DummyListItem` type in Docx/Parse.hs. In
retrospect, this seems like it mixes parsing and iterpretation
excessively. What's *really* going on is that we have a list item
without and associate level or numeric info. We can decide what to do
what that in Docx.hs (treat it like a list paragraph), but the parser
shouldn't make that decision.

This commit makes what is going on a bit more explicit. `LevelInfo` is
now a Maybe value in the `ListItem` type. If it's a Nothing, we treat
it as a ListParagraph. If it's a Just, it's a normal list item.
