Alerts - Getting alerts on status change Ongoing -> Escalating

### Problem Statement

In order to get alerted on priority issues, I need to know if issues that are ongoing go into the status of Escalating.
Currently it's only for Archived -> Escalating.

This also would need a status flow change as I don't think we support Ongoing -> Escalating statuses at this moment

### Solution Brainstorm

According to https://github.com/getsentry/sentry/issues/59868 it seems that there are some plans to have it from New -> Escalating. I would like to request adding this step as well
