Don't merge draft PRs

vercel/next.js#13193

I was surprised to see this PR was merged. Work wasn't completed actually

It appears merge.require_automerge_label is disabled on that repository, so as long as the pull request meets all GitHub Branch Protection requirements it will be merged.

Enabling merge.require_automerge_label would make it so Kodiak only merges pull requests with the automerge label, but if this can't be changed, there's a couple workarounds.

One workaround is to move the pull request into a "draft" state. GitHub does not allow draft pull requests to be merged.

Another option is to put "WIP:" in the title, which will prevent Kodiak from merging the pull request based on merge.blacklist_title_regex.

Thank you for the links! I must've clicked "Ready for review" by accident. GitHub is not showing when that happened in timeline so I'm not sure if I did it or someone else. Turns out GitHub doesn't allow merging draft PRs from the UI. if there is a bug in GitHub API that allows to do that then maybe this is an actual issue, otherwise I think this is a false alarm

Thanks! 💞
