A follow up on #2485. When importing anything from @reduxjs/toolkit@2.0.0-alpha.2, typescript cannot resolve types when tsconfig.json's moduleResolution is set to node16 or nodenext.

I found that adding the extension .js to the declaration imports resolved the issue. For example....

In my file: ./node_modules/@reduxjs/toolkit/dist/index.d.ts
export { createSlice, } from './createSlice'; -> export { createSlice, } from './createSlice.js';

Two suggestions for a fix: First, maybe the easiest, is add a post build script to add the extensions to the output. Or second, a search and replace to add the extensions to the all the relevant source files. Want to get some thoughts on a direction before attempting a PR. Maybe there's a better way.

I tried looking to see if typescript can just add them while compiling... but didn't find anything that could.
