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): update miskatonicstudio/goat digest to 49b21c1 - autoclosed" vs. "chore(deps): update miskatonicstudio/goat digest to 49b21c1"). Please update the pull request title accordingly to avoid surprises.
