Multiple editors squashed into a single string, which Typst doesn't accept (too many parts error)

[Enric Morales]

• papis version ($ papis --version or commit number):

git main

how to reproduce the issue

Command and output of papis --log INFO <command>:

papis export --format typst

During my papis -> typst export for a deliverable, I realised that, for one of my references, the editor wasn't formatted properly in the resulting yaml, making Typst throw a "too many parts" error.

Expected:

Multiple editors have to be put into a list for Typst to be happy.
