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 ("feat(deps): bump sigs.k8s.io/cluster-api from 1.4.0-beta.2.0.20230524193452-89a36acc3c3f to 1.6.0-beta.1" vs. "feat(deps): bump sigs.k8s.io/cluster-api"). Please update the pull request title accordingly to avoid surprises.
