ci: release titles use bare vX.Y.Z; bump action versions

The release-create step inherited GITHUB_REF_NAME as the title, so v0.5.0
ended up published as 'swoop-v0.5.0' while v0.4.x were titled 'v0.4.0' /
'v0.4.1'. Pass --title v${VERSION} explicitly so future releases stay
consistent. Tag still ships as swoop-vX.Y.Z (publish job and PyPI parser
depend on that prefix).

Also bump checkout/setup-python to Node 24-compatible versions to silence
the deprecation warning on every CI run.
