[External Status Checks] Replace "approved" with "passed" in API responses
Problem to solve
External Status Checks briefly used the term "approved" before we changed to use the term "passed". During that brief time, "approved" was used in the API (see "status": "approved"
in documentation examples). Now we have mixed use of pending/approved and pending/pass/fail.
Proposal
Replace "approved" with "passed" in External Status Checks API responses and documentation as discussed elsewhere.
