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?

从关联的 GitHub Actions run 开始，检查 smoke-test workflow 的 notification step 和 Python matrix。确认当前失败如何产生独立的 job alert，然后调整 workflow，使一个 alert 表示一次失败的 run，而不是每个失败的 matrix job；使用包含多个失败的 matrix run 验证其行为。
