feat(ci): Auto add needs-triage label on bug open (#30512)

## **Description**

We use the stale bot in order to make sure we close out issues which
have been open and waiting on additional information from reporters for
too long. However, sometimes this can be the case for issues that we
just haven't had an opportunity to follow back up on. We feel a couple
of process improvements can make this better.
