Update `create` doc with proper default values

Motivation and Context

Mixed default values for create between cli doc, cordova-android and cordova-ios.

Description

After reviewing the various values used in cordova-android and cordova-ios for create here are my suggested proper defaults:

• id / package name: io.cordova.helloCordova
• name / project name: Hello Cordova

These are the most common values already used but not always ; see linked PRs to fix this situation (apache/cordova-ios#1100, apache/cordova-android#1213).

Testing

in cordova-android and cordova-ios respectively

@NiklasMerz you are right :/ I looked for create values in cli, android and ios but it seems I missed the template is elsewhere... like in cordova-lib and or cordova-create ... ; I'm on it.
