chore: fix duplicate plugin warning and disable snapshots (#378)

* Don't use snapshots anymore since we don't publish them and we don't
use them for 'integrate at HEAD' development
* Consolidate the duplicate definition of the antrun plugin to eliminate
maven warning

## Summary by CodeRabbit

* **Chores**
* Updated release configuration settings across main and release branch
configurations.
* Reorganized Maven build profile configuration to improve build process
consistency.
