[Bug]: ng add @o3r/design does not work

[vscaiceanu-1a]

Package name

design

Package version

10.2.1

Reproduction steps

npm create @o3r my-workspace
cd my-workspace
ng g app webapp
ng add @o3r/design --project-name webapp

Current result

In angular.json

• "useOtterDesignToken": true, is added for all projects. Shouldn't it be only for webapp?
• generate-css builder is not added
  Also, no template files are added to the project (design-token.custom.json and theme.scss)

Expected result

In angular.json

• "useOtterDesignToken": true, is added only for webapp?
• generate-css builder is added for webapp
  Template files are added to the project (design-token.custom.json and theme.scss)
