Currently, when executing npx sb@next init in a fresh Ember 5 project, the CLI aborts and returns the following error:

Looks like this line doesn't widen the support for version 5 and above:

https://github.com/storybookjs/storybook/blob/5a83f53ee2040e2a60af83999ad574c8c29ad208/code/frameworks/ember/package.json#L54

should be:

"ember-source": "~3.28.1 || >=4.0.0",
