[4.0] non-optional react-compiler-runtime peer dependency.

Hi,

Getting this warning when installing @apollo/client@4.0.0-rc.0 in a non-react project:
```bash
warning " > @apollo/client@4.0.0-rc.0" has unmet peer dependency "react-compiler-runtime@19.1.0-rc.2"
```

This might have been missed as an **optional** peer dependency.
