Error when using cordova-simulate

# Bug Report

## Problem

### What is expected to happen?
Start simulator in browser when debuging with VSCode

### What does actually happen?
Cannot launch simulator in web browser with VSCode

## Information
VSCode cordova uses package cordova-serve that calls Api class from each platform with no parameters. In cordova-android the root definition was changed from `this.root = path.resolve(__dirname, '..');` (v.9.1.0) to `this.root = platformRootDir;` (v.10.0.1).

When trying to set the app main path (line 66) `const appMain = path.join(this.root, 'app', 'src', 'main');` because the first parameter is undefined.

### Command or Code

### Environment, Platform, Device

### Version information

Cordova: 10.0.0
Cordova-android: 10.0.1
SO: Windows 10 PRO

## Checklist

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

Start at the cordova-android Api class and the app-main lookup described at line 66, then trace how cordova-serve invokes that class without parameters. Reproduce the VSCode browser-simulator launch with Cordova 10.0.0 and cordova-android 10.0.1; done means the simulator starts in the browser without the undefined-path error.
