Update with-redux example tsconfig to use strict: true (#45325)
I was updating one of my old next.js v3 apps to v13, and decided to play
around with RTK. Using the with-redux example sort of sets users up for
some weird typing issues as mentioned here:
https://github.com/reduxjs/redux-toolkit/issues/2862
I found that github issue _after_ reading through all the official RTK x
TS docs, and it seems it could have all been avoided with stricter
typing. I'm hoping RTK can add this bit to their docs soon.
