Describe the bug
I receive the following error when creating a new Angular Storybook project:

 Error: Could not find a default project in your Angular workspace.
Set a defaultProject in your angular.json and re-run the installation.

To Reproduce
Steps to reproduce the behavior:

1. Run npx sb init and choose ANGULAR from options, or run npx -p @storybook/cli sb init --type angular
2. After the message Adding Storybook support to your "Angular" app, see the following error:

 Error: Could not find a default project in your Angular workspace.
Set a defaultProject in your angular.json and re-run the installation.

Expected behavior
The Angular project to be successfully installed

I'm not sure, but did you execute npx sb init command in an existing angular project ?

Use the Storybook CLI to install it in a single command. Run this inside your existing project’s root directory:

Ah, thanks @ThibaudAV. I was expecting an empty Angular shell, but it makes sense that isn't Storybook's job.
