Update util.typ

[ParadaCarleton]

I think this fixes #13. But because Typst is too new to have stuff like testing frameworks, it's a bit hard to know :sweat_smile:

It should be possible to set up a very basic GitHub workflow to test whether anything fails to compile, though. (@laurmaedje would you happen to have code on hand for this?)

There are already some examples in which this probably also fails. I just didn't check them since I was in a hurry. But adding some CI would be awesome and should be "relatively" simple now that png export is supported.

This unfortunately reintroduces #9. I think that if figure.has("caption") { figure.caption.body } is the right thing to here as suggested in #13. If you want to update this PR, I'm happy to merge it later (after checking the sample files this time 😅).

When I tried that approach, I got:

error: function `figure` does not contain field `has`
   ┌─ lemmify/src/util.typ:24:19
   │
24 │   body = if figure.has("caption") { 
   │                    ^^^

It should have been if fig.has("caption") { fig.caption.body }.

It should have been if fig.has("caption") { fig.caption.body }.

Thanks!

I accidentally opened two PRs so I'm gonna close this now :sweat_smile:
