APA bibliography (and possibly others) not properly formatted

[mvuorre]

Using csl: https://www.zotero.org/styles/apa (etc) doesn't include hanging indents (citeproc: true). Also when citeproc: false bibliographystyle: apa has similar issue. The latter is an upstream Typst issue.

For now the fix is

format:
  preprint-typst:
    include-before-body:
      - text: "#show <refs>: set par(hanging-indent: 1.4em)"
