chore: `npm run format`

[81reap]

I found these files were not formatted when creating this other PR for negative numbers. Raising as a separate PR here to break up the changes.

$ git clone https://github.com/hegemonic/catharsis.git
$ git checkout -b format
$ npm install
$ npm run format
$ git add .
$ git commit -m "chore: `npm run format`"
$ gh pr
