derivate isn't in Word List

[cwfitzgerald]

A pretty simple one, was just surprised it wasn't in the word list. typos wanted to correct derivate (i.e. the nominalization of "to derive") to derivative.

Thanks for this awesome tool (we just started using it in wgpu)!

(I didn't put this in #921, as that only seemed to be for new corrections)

Thanks for pointing this out!

We added a list of english words to prevent this but somehow this wasn't in the list and I wonder what other words we are missing...

Nice, thanks! Will report any others if I find them
