Feature Request

Motivation Behind Feature

Currently the user does not really see what platform version was installed, only what "version" was pinned and used with cordova-fetch:

E:\Projects\throwaway\cordovaElectronDevice2  ([email protected])
λ cordova platform add browser
Using cordova-fetch for cordova-browser@^6.0.0
Adding browser project...
Creating Cordova project for cordova-browser:
        Path: E:\Projects\throwaway\cordovaElectronDevice2\platforms\browser
        Name: HelloCordova
Discovered plugin "cordova-plugin-whitelist" in config.xml. Adding it to the project
Installing "cordova-plugin-whitelist" for browser
Adding cordova-plugin-whitelist to package.json

E:\Projects\throwaway\cordovaElectronDevice2  ([email protected])
λ cordova platform add electron
Using cordova-fetch for cordova-electron@^1.0.0
Adding electron project...
Creating Cordova project for cordova-electron:
        Path: E:\Projects\throwaway\cordovaElectronDevice2\platforms\electron
        Name: HelloCordova
Installing "cordova-plugin-whitelist" for electron

Feature Description

The output should have an additional line that could read Installed [email protected] or similar.
