Subject: [PATCH] Fix check of "reduce motion" setting on android (#36508)

Summary:
On Android `AccessibilityInfo.isReduceMotionEnabled()` returns false even when "Disable Animations" is enabled. This fixes https://github.com/facebook/react-native/issues/31221.

[ANDROID] [FIXED] - Fix check of "reduce motion" setting on android

Pull Request resolved: https://github.com/facebook/react-native/pull/36508

Test Plan: Have some code logging the value of `AccessibilityInfo.isReduceMotionEnabled()` or using it to change the UI. Run that code on Android without and with "Disable Animations" enabled. See the value is always `false` without the fix, but changes to `true` when  "Disable Animations" is enabled with the fix.
