PhosphorIcon 2.0.9 - require() of ES modules is not supported
In our Design System we have an icon package that uses PhosphorIcon. This package is built both in cjs and esm.

With the 2.0.9 version, presumably after the insertion of `type: “module”` in the `package.json` file,  we encountered this error when trying to build a Next.js app with our DS icon package.

```
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /app/node_modules/@phosphor-icons/react/dist/index.umd.js
require() of ES modules is not supported.
require() of /app/node_modules/@phosphor-icons/react/dist/index.umd.js from /app/node_modules/@docsity/ui-kit-icons/lib/cjs/index.js is an ES module file as it is a .js file whose nearest parent package.json contains “type”: “module” which defines all .js files in that package scope as ES modules.
Instead rename index.umd.js to end in .cjs, change the requiring code to use import(), or remove “type”: “module” from /app/node_modules/@phosphor-icons/react/package.json.

Reverting to 2.0.8 solved the problem but we are concerned about the impossibility to use the latest version of your library if we can't find a solution.

We are using:
yarn 1.22.19
react 17.0.2
typescript 4.3.2
lerna 4.0.0
