Polyfill library throwing react-17 dependency warning

[TJHeeringa]

create-react-context throws a dependency warning. Create react context is a polyfill library, so you could consider removing it.

create-react-context should be removed if this react-form-validator-core is for React 17/18 , especially for the v3. It could be left for the older versions that support React16
