Use patch-package to update prettier to use one prop per line and add a line break before else

1. yarn add -D patch-package postinstall-postinstall
2. mkdir patches and place this gist in the directory (you might need to update the version in the name)
3. patch-package to apply the diff
   Optional 4. Add a "postinstall": "patch-package" script to your package.json to keep applying the patch after updates.

See ds300/patch-package: Fix broken node modules instantly 🏃🏽‍♀️💨 and Using npm patch-package - YouTube for more about patch-package

Thanks to Shinigami for the idea.

And now, I can finally unsubscribe from those prettier issues/discussions :)
