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?

從關聯的 GitHub Actions run 開始，檢查 smoke-test workflow 的 notification step 和 Python matrix。確認目前失敗如何產生個別的 job alert，然後調整 workflow，使一個 alert 代表一次失敗的 run，而不是每個失敗的 matrix job；使用包含多個失敗的 matrix run 驗證其行為。
