Fix getDevSupportManager() in ReactDelegate

Summary:
In facebook#43520, this was moved to supply with the relevant DevSupportManager, however this check for `useDeveloperSupport` is already part of https://github.com/facebook/react-native/blob/0.74-stable/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/ReactInstanceManager.java#L263

https://github.com/facebook/react-native/blob/0.74-stable/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/devsupport/DefaultDevSupportManagerFactory.java#L68-L70

Having this check here was causing early exit for Bridge RELEASE mode instead of returning the ReleaseDevSupportManager.
