Migrate to PackageCloud: restore Axion, change groupId to com.rundeck.plugins, upgrade to Java 17

- Changed groupId: org.rundeck.plugins → com.rundeck.plugins
- Updated Axion with prefix='' (no 'v' prefix)
- Added versionCreator 'simple' to Axion
- Updated nexusPublishing.packageGroup to com.rundeck.plugins
- Added PackageCloud publishing configuration
- CRITICAL: Upgraded from Java 11 to Java 17 for Grails 7 compatibility
- Version now managed dynamically from git tags

Based on origin/main (includes all post-v1.8.6 commits)
