Make quote actions not break with c++ language (#3925) o-x-e-y

* Make quote actions not break with c++

c++ currently obviously has `+` symbols which means stuff like quote ratings break because of the validation regex. I feel like changing `\w` straight to `.` would also be fine since languages and their names get approved manually, but this should work fine for now

* fix silly mistake

a `.regex()` got removed for whatever reason

* Fix prettier bug

* remove unnecessary spaces
