yarn lint is not running

[bb]

In preparation for #121 I tried running through the contributing guidelines, however, the step yarn lint was not running successfully on a fresh checkout. The commands given before that were fine.

yarn lint
yarn run v1.22.10
$ eslint --ext .js,.ts,.tsx .

Oops! Something went wrong! :(

ESLint: 7.12.1

ESLint couldn't find the config "react-app" to extend from. Please check that the name of the config is correct.

The config "react-app" was referenced from the config file in "/Users/bb/src/meilisearch/instant-meilisearch/playgrounds/react/package.json".

If you still have problems, please stop by https://eslint.org/chat/help to chat with the team.

error Command failed with exit code 2.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

After yarn add -D eslint-config-react-app, it still failed because of eslint-plugin-flowtype (and a few others) it runs... but it does not terminate, at least not within a few minutes:

$ yarn lint
yarn run v1.22.10
$ eslint --ext .js,.ts,.tsx .
Warning: React version was set to "detect" in eslint-plugin-react settings, but the "react" package is not installed. Assuming latest React version for linting.

It just keeps one core busy at 99% CPU.

I'm using node 14.14.0 and these are my changes compared to current master:

I also upgraded all outdated packages but it did not help. I created a PR to share the current WIP.
