🐛 Bug Report

TS says createInstance exists on an instance, but it doesn't.

To Reproduce

StackBlitz

Open the console and see the error.

import i18next from 'i18next';

const instance = i18next.createInstance()
instance.createInstance(); // errors at runtime, but TS is fine with it

Expected behavior

TS shows an error when trying to use createInstance on an instance.
