ci: guard windows/linux uploads to tag pushes, artifacts on test runs

Mirror the macOS job's guarding on the windows and linux jobs so a
workflow_dispatch (branch) run never publishes a junk release/tag named after
the branch: upload to the release only on tag pushes, otherwise upload the
built installer/package as workflow artifacts. Also derive their version the
same safe way ("test" on non-tag runs) so a branch ref with "/" can't break
the installer filename or Arch pkgver.
