fix: bump dash-form dated URLs on version changev1.1.3

--hintfile -V and --new -V only substituted the packaged underscore form
of the old version, so download URLs using the upstream dash form (dates
like 2026-07-07, tags) kept pointing at the old tarball and their md5
went stale. Now both the underscore and dash variants of old->new are
rewritten. exploitdb was the trigger case.

Tests T74 (--hintfile) and T75 (--new) cover the dashed-URL bump.

Release v1.1.3.
