Automatically action on advisories that change to false positive (and/or other?)

Release notes

Problem to solve

In some cases, we might have an advisory that later becomes false positive, and can confuse customers

see #349077 (closed)

It would be good to update/action these

Proposal

Change, and note (comment) a status change on findings that are later false positive.

maybe also comment on any linked issues?

perhaps this could be for any major update?
