Invalid "exports" target "src/once.js" defined for "." in the package config

Opened MR with the fix

I also see this issue, in Storybook 8.2. I do not see it when using @drupal/once with Storybook 8.1.

This change resolves the issue on 8.2 and doesn't introduce errors in 8.1.

Thank you I have same issue and it resolved it, I think we can move on to RTBC

We encounted this same issue with Storybooks and tested that the same change fixes the issue. So +1 for RTBC.

Could this be merged and a new release done both to drupal.org and https://www.npmjs.com/package/@drupal/once?
