Create-react-app: Immer dependency in react-dev-utils is outdated and needs to be updated

[markerikson]

Describe the bug

The react-dev-utils package currently depends on [email protected]:

https://github.com/facebook/create-react-app/blob/edc671eeea6b7d26ac3f1eb2050e50f75cf9ad5d/packages/react-dev-utils/package.json#L68

That version is _extremely_ outdated, since Immer is now at v6.x:

https://github.com/immerjs/immer/releases

Since many apps now use Immer (including those built with Redux Toolkit), this can lead to multiple versions of Immer being included in node_modules. In at least one instance, it resulted in a weird situation where the RTK-requested immer@6 dependency was nested while the react-dev-utils-requested [email protected] version was hoisted, and then TS failed to compile the user's project:

https://github.com/reduxjs/redux-toolkit/issues/459

Given that Immer's API has basically stayed the same and that it's only being used in one spot in react-dev-utils, this should be an easy upgrade.
