RefForwardingComponent removed in react 18

[PerfectionVR]

Intended outcome:
No errors

Actual outcome:

Running the following command

tsc --project tsconfig.json --noEmit

on a typescript project would result in the following issues.

node_modules/mobx-react-lite/dist/observer.d.ts:5:84 
- error TS2694: Namespace 'React' has no exported member 'RefForwardingComponent'.

} ? C extends React.RefForwardingComponent<infer TRef, infer P> ? C & React.MemoExoticComponent<React.ForwardRefExoticComponent<React.PropsWithoutRef<P> & React.RefAttributes<TRef>>> : never : C & {

How to reproduce the issue:

Apolegies for the lack of codesandbox, however, this is related to other projects that are having similar issues when upgrading to react 18.

This comes down to this particular commit...
DefinitelyTyped/DefinitelyTyped#56210

RefForwardingComponent was removed with no replacement, hopefully this can be fixed one way or another.
