* Add the `notify-email` column / NotifyEmail to ActionRun and set it:
* services/actions/workflows.go `Dispatch`
* services/actions/schedule_tasks.go `CreateScheduleTask`
* services/actions/notifier_helper.go `handleWorkflows`
* Only send an email if the workflow has `enable-email-notifications: true` by having `MailActionRun` return immediately if `NotifyEmail` is false.
* Ignore or silently fail on `enable-email-notifications: true` parsing errors. Reporting such errors belongs in workflow validation, not when it is evaluated for the notifications.
* Add unit and integration tests.
