ci: package the Decky zip and publish Gitea releases per version

- scripts/package.py builds out/mudfish-decky-<version>.zip with the
  mudfish-decky/ folder Decky expects (runtime files only).
- scripts/gitea_release.py creates release v<version> and uploads the zip,
  skipping versions that already have a release.
- Jenkinsfile uses the organization folder's gitea-ysj7705 token.
