fix: skip network monitoring for watchOS

[lawmicha]

Issue #

#3220

Description

Uses the changes from aws-amplify/aws-appsync-realtime-client-ios#139. See this for more details.

Testing

We need to run this app on a physical device to fully verify that the issue is fixed. However, running on a simulator, we can check that there are no logs around network monitoring.

The logs around networking monitoring looks like this:

[RealtimeConnectionProvider] Status: inProgress. Connectivity status: unsatisfied

Running the app on a simulator and then calling DataStore.start() shows that there are no "Connectivity" related logs
