fix(virtualized-lists): react-test-renderer is not a runtime depend…

…ency (facebook#37955)

Summary:
Installing `react-native` 0.72.x causes a warning about `react-test-renderer` because `react-native/virtualized-lists` has declared a peer dependency on it. As far as I know, it is not used for anything but tests.

```
➤ YN0002: │ react-native@npm:0.72.0-rc.6 [292eb] doesn't provide react-test-renderer (p5a2fb), requested by react-native/virtualized-lists
```

Note that while many package managers default to warnings in this case, there are still a number of users out there for which this is an error.

[GENERAL] [FIXED] - `react-native/virtualized-lists` does not need `react-test-renderer` at runtime
