Upgrade json-schema version to 0.4.0

Editor assessment

`chore(deps): upgrade json-schema version to 0.4.0 (#4543)` names the dependency and the target version precisely; deps scope and chore type are accurate. No body explains the motivation for the pin — likely a security advisory — which would have been the instructive part, a modest gap. The trailing PR reference is clean, and nothing is malformed. Imperative verb, no trailing period, compact. Correct, legible, and complete at the subject level: a publishable maintenance example with a minor rationale gap.
