Creating a new app is broken with node 17 because of postcss version

[PawelMorawian]

Describe the bug

After creating a new app with create-react-app it won't start:

yarn run v1.22.17
$ react-scripts start
node:internal/modules/cjs/loader:488
      throw e;
      ^

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/tokenize' is not defined by "exports" in /home/pawel/dev/baz/node_modules/postcss-safe-parser/node_modules/postcss/package.json

}

Node.js v17.1.0
error Command failed with exit code 1.

It seems that the version of postcss-safe-parser used by create-react-app is not working with node 17: postcss/postcss-safe-parser#29

Steps to reproduce

1. Install node 17
2. Create a new app with create-react-app foo
3. cd foo
4. yarn start or npm start
5. The app won't start, the error above is the reason
