Build is failing in CI

The main branch is failing with this error:

$ npm test

Seems to be related to xojs/xo#718

sindresorhus/eslint-plugin-unicorn#2076 seems to indicate that upgrading to eslint-plugin-unicorn v46.0.1 should fix the problem. Annoyingly, it's still failing after I update to that newer version.

I also tried updating the version of xo to 0.55.0, which is supposed to fix the issue. That raises the minimum required node version to 16, though. This library currently requires v14. Upgrading xo causes failures for new reasons:

$ npm test
