Github workflow: Send e-mail on job error

This job is designed to be silent when Cirrus-cron executions pass.
Unless specifically instructed, the workflow itself will also remain
silent if there's an error.  Fix this by catching workflow errors and
sending a notification e-mail containing a link to the failed run.  This
also requires listing the recipient addresses directly in the workflow.
Otherwise (as previouslly implemented) the value would not be retrieved
if/when any previous step raised an error.

**Note**: Due to the way this workflow is implemented, there is no way
easy way to test it other than directly on the `main` repo. branch.
