chore(styles): drop deprecated word-wrap property (#854)

According to [MDN](https://developer.mozilla.org/en-US/docs/Web/CSS/overflow-wrap):

> The property was originally a nonstandard and unprefixed Microsoft extension called word-wrap, and was implemented by most browsers with the same name. It has since been renamed to overflow-wrap, with word-wrap being an alias.

I think we can safely ditch `word-wrap` for `overflow-wrap` everywhere and save a few bytes.
