Renamed middlewares to middleware consistently
- This is a minor bugbare, but it will affect some configuration I'm about to do for c8
- I've been wanting to do it for ages, middleware is plural all on it's own so it's an odd affectation in our codebase
- This also only exists in 2 places, everywhere else we use "middleware"
- Sadly it did result in a lot of churn as I did a full find and replace, but consistency is king!
