chore(aci milestone 3): migrate alerts with erroring actions (#90706)

The logic change is in #90688;
I've just copied the entire migration over. The only other change is in
how we fetch the rule querysets, which I've highlighted.

The migration was run this morning, but ran into an issue with the
actions https://sentry.sentry.io/issues/6578271039 that was fixed in
#87933. The fix to the actions
was propagated to the migration in
#90688. To rerun the migration,
we've made a separate script that is a copy-paste of the old migration,
but with the rule fetching updated.
