Scheduled GHA notifications

[Zidious]

We have several GHA's that are on a CRON schedule, if the workflow fails the team is not notified of the failure instead an individual is notified:

Notifications for scheduled workflows are sent to the user who initially created the workflow. If a different user updates the cron syntax in the workflow file, subsequent notifications will be sent to that user instead. If a scheduled workflow is disabled and then re-enabled, notifications will be sent to the user who re-enabled the workflow rather than the user who last modified the cron syntax.

To get around this 1-bus factor, we can create a new GHA that is called on failure() that can notify a particular slack channel of what repo and workflow failed.
