Copied from https://github.com/apache/cordova/issues/252
# Bug Report
When I use a clean installation of my project and run `cordova platform add android` my `package.json` file gets changed significantly, and incorrectly.

### What is expected to happen?
`package.json` should be respected

### What does actually happen?
`package.json` get overwritten. Also dependencies are getting the wrong version

## Information
It might be because I have the packages registered in dependencies and not devDependencies, I don't know...

### Command or Code
Project can be found here:
https://github.com/IsraelHikingMap/Site/tree/master/IsraelHiking.Web

### Environment, Platform, Device
Currently testing on Android

### Version information
Cordova cli: 10.0
cordova-android: 9.0

This started happening after the upgrade to 10.0 and android 9.0.

## Checklist

- [x] I included all the necessary information above

Reproduce the issue using the linked IsraelHikingMap/Site project with a clean installation and `cordova platform add android`. Compare the resulting package.json with its original dependencies and versions, then trace the platform-add package update behavior. Done means package.json is preserved appropriately and dependency versions are not changed incorrectly.
