Immer dependency in react-dev-utils is outdated and needs to be updated #8750
Description
Describe the bug
The react-dev-utils package currently depends on immer@1.10.0:
That version is extremely outdated, since Immer is now at v6.x: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 immer@1.10.0 version was hoisted, and then TS failed to compile the user's project:
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.
