Subject: [PATCH] Update custom "exports" conditions in Jest environment
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
Updates the default set of `"exports"` condition names in our `ReactNativeEnv` for Jest, so that it aligns with the defaults in React Native CLI (https://github.com/react-native-community/cli/pull/1862).

Also includes a subtle update to how this is accomplished. Instead of overriding `exportConditions()`, we assign to the underlying class property — this allows users (once https://github.com/facebook/jest/pull/13989 is merged) to override `customExportConditions` via [`testEnvironmentOptions`](https://jestjs.io/docs/configuration#testenvironmentoptions-object).

```js
  preset: 'react-native',
  testEnvironmentOptions: {
    customExportConditions: ['test', 'react-native'],
  },
```
