Update pinned action versions in Launchable setup

The commit SHAs did not match their version comment tags, as
flagged by zizmor ref-version-mismatch. Update all three actions
to their latest releases with correct SHAs.

- actions/setup-python v5.0.0 -> v5.6.0
- actions/setup-java v4.0.0 -> v4.8.0
- gacts/run-and-post-run v1.4.0 -> v1.4.3
