ci: implement automatic SNAPSHOT version generation for continuous deployment (#625)

- Modified early-access workflow to automatically append -SNAPSHOT to versions
- Skip snapshot releases for already-released versions (with git tags)
- Skip snapshot releases for RC and existing SNAPSHOT versions
- Configure JReleaser to mark SNAPSHOT versions as prereleases
- Enable continuous deployment for every push to main branch

Fixes #625
