fix(docs): Omit AsyncStorage from basic ReactotronConfig.js (#1479)

## Please verify the following:

- [X ] `yarn build-and-test:local` passes
- [X ] I have added tests for any new features, if relevant
- [X ] `README.md` (or relevant documentation) has been updated with
your changes

## Describe your PR

Without AsyncStorage dependency, the instruction in "Step 2 -
Initialization" simply doesn´t work if the developer app doesn´t already
use AsyncStorage, since it does
´Reactotron.setAsyncStorageHandler(AsyncStorage)´

Since AsyncStorage isn´t required for the base configuration, remove it.
