ci: Add release-please for automated releases

- Add release-please GitHub Action workflow that:
  - Creates release PRs automatically from conventional commits
  - Publishes to NuGet when releases are created
- Add release-please-config.json with simple release type
- Add .release-please-manifest.json tracking current version
- Update pyproject.toml version to 5.0.0-alpha.11
- Remove old publish.yml (functionality merged into release-please.yml)
