Add Angular Builder Codemods

[valentinpalkovic]

Closes #20947

What I did

Added two auto migrations for Angular. The first one will output a prompt to notify the user that the migration must be done manually in multi-project Angular workspaces. The other one will automatically configure the angular.json properly to use the Storybook Angular builder instead of directly calling storybook dev or storybook build.

How to test

1. Select an Angular project with Angular v. 14 or higher.
2. Select a project with several Angular projects specified without having a root project defined in the angular.json -> Run the upgrade command. No auto-migration is triggered. Instead, the user will see a notification to upgrade manually.
3. Select a project with one Angular project or one root Angular project -> Run the upgrade command. The auto-migration should add some entries to the angular.json to set up Storybook properly. Additionally, the commands in the scripts section of the package.json are adjusted as well.
