[Bug]: @o3r/testing should not be installed by default for generated application

[cpaulve-1A]

Package name

workspace

Package version

11.*

Reproduction steps

Add @o3r/workspace to a project and generate an application with ng g application

Current result

A prompt informs the user @o3r/testing will be installed and asks the user if they want a jest setup.

Expected result

This dependency should not be mandatory as it is only used to activate the visual testing masks from the chrome extension..
@o3r/testing should be optional in @o3r/application and required at runtime.
