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 zgosalvez/github-actions-ensure-sha-pinned-actions from 3.0.18 to 3.0.21" vs. "chore(deps): bump zgosalvez/github-actions-ensure-sha-pinned-actions"). Please update the pull request title accordingly to avoid surprises.
