ERESOLVE unable to resolve dependency tree with npm@7 and react@17

A clean install with npm@7+ and react@17+ throws the following error message and can currently only be fixed with `npm install --force` as workaround.

```sh
$ npm install
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

Update peerDependencies in your `package.json` should do the trick:

```diff
- "react": "^15.3.0 || ^16.0.0",
+ "react": "^15.3.0 || ^16.0.0 || ^17.0.0",
