I18n/23/I18next Replace Keyswithseparator With Joinkeys

Renaming types or functions can be part of an effort to clarify the library's API, deprecate old functionality, or introduce new features. In this case, KeysWithSeparator has been renamed to JoinKeys. This means wherever KeysWithSeparator was used in the codebase, it needs to be replaced with JoinKeys.

Example

Before

import { KeysWithSeparator } from 'i18next';

const myTranslationFunction = (key: KeysWithSeparator < string > ) => {
  // Function body remains the same
};

After

import { JoinKeys } from 'i18next';

const myTranslationFunction = (key: JoinKeys < string > ) => {
  // Function body remains the same
};
