The pull request has only one (non-merge) commit and in this case Github will use it as the default commit message when merging. The pull request title doesn't match the commit though ("chore(deps): Bump github.com/kyverno/kyverno-json from 0.0.3-alpha.2 to 0.0.3" vs. "chore(deps): Bump github.com/kyverno/kyverno-json"). Please update the pull request title accordingly to avoid surprises.
