```sh
yarn test --build --project devtools
```

This doesn't actually run any DevTools tests. It runs the main React tests.

Console output shows that it's choosing the wrong config:
```sh
$ yarn test --build --project devtools
$ node ./scripts/jest/jest-cli.js --build --project devtools
$ NODE_ENV=development RELEASE_CHANNEL=experimental node ./scripts/jest/jest.js --config ./scripts/jest/config.build.js
```

I wonder if this is also happening for other targets?
