docs(platform-checklist): point automation.json's ExecutionStatus mention at its source instead of restating members (#17364)

The "suspending types park the run" verify string in automation.json
hand-copied the ExecutionStatus vocabulary as eight pipe-separated
members and was missing `refused` (#14945), which the enum has carried
as a ninth, terminal member since. Retyping a fresh nine-member list
would re-arm the same trap the moment a tenth member lands, so the
parenthetical now names the declaring file instead of restating
members.
