Smoke test failure sends one message per python version

e.g. https://github.com/astronomy-commons/hipscat-cloudtests/actions/runs/8015681836

The action failed for python 3.9 and 3.10, and was cancelled for 3.11. We received two alerts, but they each had the same action/run URL, so it looked like a totally duplicated message.

Would it be possible to have the notification step happen ... outside the python matrix scope? and send an alert if the run fails, not just for each job that fails?

リンクされた GitHub Actions run から始め、smoke-test workflow の notification step と Python matrix を調査します。現在、失敗によって個別の job alert が生成される仕組みを確認し、その後、失敗した matrix job ごとではなく、失敗した run を 1 つの alert で表すように workflow を調整します。複数の失敗がある matrix run で動作を検証します。
