[ISSUES] Update ci:sev template to include a note about ci: disable-autorevert label (pytorch#165459)

We noticed that disabling autorevert in any and all ci:sevs is too impactful, as ci: sevs are sometimes created just to communicate an action or a impactful change. But sometimes durring a SEV we might not want to disable autorevert anyways, a example is a ci: sev impacting jobs we don't use as basis for autorevert.

So, a note is added reminding the ci:sev author to optionally add this tag to disable auto-revert

Note: using this opportunity to fix the ci: disable-autorevert issues. As it is best for the title to be simple and the displayed message in the GitHub interface to be decorated with emoji :)
