[Bug] Dependency conflicts on freshly-created ember app

[newt-beach]

Describe the bug

When I create a new ember app and follow the instructions here, I make it to ember install @storybook/ember-cli-storybook at which point I get the following errors:

I had a similar issue in a fresh installation past month. Let me check again, I had an improvement in my code, I think there was needed an extra dependency to solve the problem.

@collinsmwade AFAIK, I don't think you need to run npx storybook init if you're going to install this dependency after it.
