Storiesof-to-csf codemod throws cannot find core-js module

[LeBenLeBen]

Describe the bug
When running the codemod script to migrate storiesof stories to csf format, the command throws the following error:

Error: Cannot find module 'core-js/modules/es6.string.starts-with'

I've already tried everything suggested in #8267 but nothing worked so far.

To Reproduce
Steps to reproduce the behavior:

1. Run npx -p @storybook/cli@next sb migrate storiesof-to-csf --glob "**/*.stories.js" in a project with some Storybook stories in the "storiesOf" format
2. See error in the console

Expected behavior
The command should not throw

System:

npx -p @storybook/cli@next sb migrate storiesof-to-csf --glob "**/*.stories.js"
=> Applying storiesof-to-csf: 1 files

Whoops, this is very similar to #8209, I'll let you decide if it's worth keeping separately or closed as duplicate.

Yeah closing as dupe to #8209. Thanks! 🙏
