chore: Add distribution management and enhance GitHub Actions workflow for Maven Central publishing

- Introduced distribution management section in pom.xml for centralized repository configuration.
- Added central-publishing-maven-plugin to both release and snapshot profiles for automated publishing to Maven Central.
- Updated GitHub Actions workflow to differentiate between release and snapshot profiles, improving deployment flexibility.
- Enhanced setup steps to dynamically set the Maven profile based on the event type (release or push).
