This is needed in order to satisfy JSR's publish requirements.

Was there an attempt to publish @eslint/core that failed because of this, and how come the problem isn't caught by the Verify JSR Publish check on the main branch?

@mdjermanovic yes, I posted in Discord about it.

There are a number of issues with jsr public --dry-run where it's not catching things that actually fail when a live publish is attempted. There are multiple bugs open in the JSR repo regarding this.

[mdjermanovic]

The change LGTM if it's needed (not sure how to verify if it isn't caught by --dry-run).

You can run npx jsr publish locally. Because we can't republish and existing version, it will go through the entire process and when it realizes the version already exists, it will skip the very last part.

Sorry, are you saying you can't reproduce before this PR? Or after?
