[Bug]: CSF-2-3 automigration scripts ignores Typescript types

[valentinpalkovic]

Describe the bug

The csf-2-3 automigration script does not transform StoryFn types to StoryObj.

Requirements:

1. StoryFn type assignments should be replaced by StoryObj.
2. The import has to be adjusted to import StoryFn instead of StoryObj

To Reproduce

1. Create a Story, which imports StoryFn from "@storybook/" and use it for a Story.

export const Default: StoryFn = () => {...}

2. Run the auto migration script

npx sb@next migrate csf-2-to-3 --glob="**/*.stories.ts" 

3. The StoryFn type is not transformed to StoryObj

Strange, I have used this script to transform all the CLI templates from CSF2 to CSF3 🤔

@valentinpalkovic I have the same issue. Not sure if this is a regression then.
