Expected Behavior

1. I expect lockfile to NOT be git ignored and be committed instead for many best practice and security reasons.
2. I expect theme to be deploy-able to Github Pages by following official guide but it fails as it expects to have a package-lock.json but it's not there because it's git ignored.

Steps to Reproduce

1. Follow the official guide
2. See your GHA fail.

Additional Information

I'd suggest to commit the lockfile by default and add a step to documentation a reminder to update the dependencies.
