Add quotes to status value (#147)

Whoops, I missed this in my review of #146. Value of status needs to be quoted.

Currently the log looks like
{"event":"github_secret_scanning", "status":success, "createdAt":"2024-10-30T17:20:07Z", "repo":"getsentry/gocd-jsonnet","pull_request":"https://github.com/getsentry/gocd-jsonnet/pull/83","actor":"IanWoodard"}
