fix(sentinelone): accept a skipped UAM update when the alert is already set (1.17.3)

The console skips an alert already in the requested state, and 1.17.2
failed every skip: re-assigning an alert to its current holder, as a
second run of the same playbook does, broke the block.

A skipped alert is now read back. Already assigned to that user, or
already carrying that status or verdict, the block succeeds with
already_assigned / already_set; otherwise it fails naming the state the
console holds.
