SSR: Wrongly published ESM code

Describe the bug

I'm the author of vite-plugin-ssr and users are reporting the following problem with PrimeReact:

file:///home/fabio/Desktop/playground/vps-cjs-issue/dist/server/entries/pages_index-page.mjs:2
import { Badge } from "primereact/badge/badge.esm.js";
         ^^^^^
SyntaxError: Named export 'Badge' not found. The requested module 'primereact/badge/badge.esm.js' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'primereact/badge/badge.esm.js';
const { Badge } = pkg;

I believe the problem is that Node.js treats the module as CJS because node_modules/primereact/badge/package.json doens't contain type: "module". A fix would be to change the file extension of node_modules/primereact/badge/badge.esm.js to badge.esm.mjs, as the .mjs reliably tells Node.js that the file is an ESM module.
