Fix broken tests

I suppose we should also update the submodules by git submodule update --remote --checkout fixtures/std locale. There are 34 failing test in https://github.com/Juris-M/citeproc-js/actions/runs/8217286827/job/22472816322 but this is not reflected in the Github Action status.

Thanks for updating such a bunch of tests.

I noticed the./locale submodule is still not updated. Is that the expected behavior? Without the update of locale, there are currently 34 failing test (see https://github.com/Juris-M/citeproc-js/actions/runs/8217286827/job/22472816322). After git submodule update --init --remote --checkout locale, only two tests are failing: label_EditorTranslator1 and label_MissingReturnsEmpty (see zepinglee@a056180 and https://github.com/zepinglee/citeproc-js/actions/runs/8245602651). I'll make a PR to the test-suite repository.
