Update Hive Android entry to reflect new Cordova-based app

As you might remember, Hive iOS is a Cordova-based app, which basically wraps Hive Web into a native shell.

To have Hive work the same across all platforms, we are now switching Hive Android to the same mechanism. A Cordova-based app for Android has just been released on Google Play (under a new id) and we are retiring the previous SPV app.

This pull request reflects these changes. The entry for Android now points to https://play.google.com/store/apps/details?id=com.hivewallet.hive.cordova (the new Cordova-based app) and the screenshots and details about risks have been changed to match the Hive iOS entry.

I hope this can be merged soon. Let me know if you have any question - thanks!
