Add flow types to AccessibilityAndroidExample.android.js

Description

AccessibilityAndroidExample.android.js does not have proper Flow types. Without Flow typing enforced, it is easy for bugs to be introduced when making changes to this file. This issue details the work to enforce Flow typing in this file.

Steps:

1. Add the @flow annotation to AccessibilityAndroidExample.android.js
2. Run flow status and fix any Flow errors that appear.
   • You can check out Flow’s getting started guide here: https://flow.org/en/docs/getting-started/
   • You can check out Flow’s React-specific documentation here: https://flow.org/en/docs/react/components/
   • An example file that is already annotated with @flow: ScrollViewExample.js
3. Bonus: Update the file to use @flow strict-local

Expected Results

AccessibilityAndroidExample.android.js is annotated with proper flow types.
