feat(triage signals): Auto Trigger Fixes "On" maps to Medium fixability threshold (#103781)

## PR details
+ For the V0, rather than running on all issues with >= event count we
are only running for issues with >= med. fixability and >= 10 event
count.
+ This will help us reuse the `_is_issue_fixable` function as is in
run_automation.
