Add a workflow to backfill the missing installers in the recent snaps…

…hots As I documented in git-for-windows/git-for-windows-automation#112, there was a problem with the recent snapshots in that the installers were not actually uploaded. That PR fixes it for future snapshots. This here workflow fixes it for existing snapshots. Signed-off-by: Johannes Schindelin <[email protected]>
