Network type not updating during runtime

When the network type changes the `type`-property should update accordingly.

When the `type`-property changes on app start and resumption only.

## Checklist

- [x] I searched for existing GitHub issues
- [ ] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Start by reproducing the supplied setInterval example on Android 8 or 9 and changing the network connection during runtime. Inspect the plugin’s Android handling of network changes and the navigator.connection.type value. Done means the type property updates while the app remains running, not only on startup or resumption.
