Reliablility report is inaccurate

I started investigating https://github.com/nodejs/node/issues/44805
when taking a look at https://github.com/nodejs/reliability/issues/388:

not ok 3789 sequential/test-watch-mode-inspect
  ---
  duration_ms: 120.67
  severity: fail
  exitcode: -15
  stack: |-
    timeout
    TAP version 13
    (node:37761) ExperimentalWarning: The test runner is an experimental feature. This feature could change at any time
    (Use `node --trace-warnings ...` to show where the warning was created)
  ...

the first PR in the Failed PR row has two CI runs prior to this report: 46819, 46808

the first CI run reports a failure for this based on the previous osx1015 run https://ci.nodejs.org/job/node-test-commit-osx/47578/ that did not actually run in this build (due to java.net.ConnectException: Connection timed out) but Jenkins still considers the child of a previous run to be the child of this run.

this obviously happened in other PRS/CI runs as well, wich makes the report links and count very hard to rely on when investigating flaky test issues

まず、nodejs/reliability#388 の信頼性レポートが、参照されている Jenkins 実行 46819、46808、47578、46857 から Failed PR、First CI、Last CI、Appeared のリンクをどのように導出しているかを追跡します。47578 の実行で失敗した接続を含め、親ビルドと子ビルドの関係を比較します。レポートのリンクと件数が実際に実行された CI 実行を反映すれば完了です。
