Labels: bug,help wanted,pnpm,automigrations,sev:S4

### Describe the bug

When running `pnpm dlx sb upgrade`, I get a migration summary of the following:

```
│   If you'd like to run the migrations again, you can do so by running 'npx storybook@next automigrate'                                  │

But, It didn't actually list out any duplicates.

### Additional context

I've used `pnpm.overrides` to avoid duplicates already.  Maybe that's why this is getting triggered?
