[Omission]: useOptimistic is documented as having a required second parameter

[denis-sokolov]

Summary

useOptimistic’s second parameter is allegedly optional (source), but the docs imply that it is required.

Page

https://react.dev/reference/react/useOptimistic#parameters

Details

Perhaps in the Reference section, Parameters, under updateFn, it could be mentioned that the function is optional, and that the returned function addOptimistic will instead be a setter (setOptimistic).
