New release for Typst 0.13

[Xexio15]

As someone mentioned in Issue #29, without the latest changes the package is unusable on latest version.

Could you make a new release with latest changes?

Thank you

I have the impression that even the latest version with patch #29 doesn't work because style continues to be used (undefined) in render for example.
I've opened a pull request #31 that should correct the problem.
