📚 Description

I figured I would try #1831 by using the nightly release, but the job did not get triggered as one of the squashed commits in the merge message contains 'chore'.

We used to have the same issue for @nuxtjs/i18n, this changes the conditional to only check start of the commit message instead of including the squashed commits. I'll check other repositories and open a PR to add this.
