Subject: [PATCH] ci(duplicate-check): only warn about the auto close the sweep
 will actually do

The notice now asks the sweep's own duplicateTarget whether the title
match would close the issue, so a two-word title no longer gets a close
warning the sweep would refuse to act on. The ask no longer promises
that a reply removes the label, since nothing does that automatically
