debugging plain js is not hitting breakpoints

### Expected Behaviour

Can debug in vscode and hit breakpoints in js actions

### Actual Behaviour

cannot

This needs to be documented, all the steps.
.vscode/launch.json needs to be included in app template
webpack-config.js should also be part of template

#### Sample Code that illustrates the problem

#### Logs taken while reproducing problem

Start by locating the app template and the referenced .vscode/launch.json and webpack-config.js files, then review how plain JavaScript actions are launched in VS Code. Document all debugging steps and ensure both files are included in the app template; done means breakpoints can be hit and the process is documented.
