Why is jest-expo not updated when I run npx expo install --fix?

I am upgrading from Expo SDK 47 to 48.
I am referring to the Expo SDK 48 Blog - Upgrading your app.

I upgraded by executing the following command and the jest-expo was not updated.

  • npm install expo@^48.0.0
  • npx expo install --fix

I would like to confirm why jest-expo is no longer updated, since the previous upgrade method (expo-cli upgrade) updated jest-expo.
