Correct patch docs: production Android builds compile RN from source

buildReactNativeFromSource: IS_PRODUCTION in app.config.js makes expo-build-properties
inject the source-build substitution at prebuild, so the ReactViewGroup.kt hunk is
active in production releases. Only local dev builds (prebuilt AAR) do not get it.

It only takes effect if we enable building React Native Android from source active in production releases. Local dev builds prebuilt in a non-production env consume
(`includeBuild` + dependency substitution in `android/settings.gradle`), or once an the prebuilt AAR from Maven Central instead, where this hunk (like any ReactAndroid
equivalent fix ships upstream. Kept so the fix is ready and documented either way. source change) has no effect - do not expect to see the fix in a local debug build unless
you prebuild with EXPO_PUBLIC_ENV=production or add the substitution block manually.
