chore(expo-router,jest-expo): Tighten react-server-dom-webpack peer requirements and bump (#41379)

kitten · vonovak · kitten · commit a6674f534d35 · 2025-12-04T15:43:21.000Z
> [!NOTE] > Backport will at least be needed for SDK 54, maybe SDK 53, if the range is compatible with it We don't need to open up the range, and can set a new minimum as of latest publishing date. We can also bump our internal version. `jest-expo` had a hard dependency on `react-server-dom-webpack` which can also be switched to a peer dependency. - Tighten peer range on `react-server-dom-webpack` and bump - Switch `react-server-dom-webpack` to optional peers in `jest-expo` and bump - CI-only  - [x] I added a `changelog.md` entry and rebuilt the package sources according to [this short guide](https://github.com/expo/expo/blob/main/CONTRIBUTING.md#-before-submitting) - [ ] This diff will work correctly for `npx expo prebuild` & EAS Build (eg: updated a module plugin). - [ ] Conforms with the [Documentation Writing Style Guide](https://github.com/expo/expo/blob/main/guides/Expo%20Documentation%20Writing%20Style%20Guide.md) --------- Co-authored-by: Vojtech Novak <vonovak@gmail.com>
