Simplify Helm workflow to build on main branch only

- Removed tag-based triggers and release creation
- Renamed workflow from helm-release.yml to helm-build.yml
- Simplified to always build and publish on main branch push
- Version always comes from Chart.yaml (no modifications)
- Removed all release-related logic and conditions
- Kept PR linting for validation
- Cleaner and simpler workflow focused on continuous delivery
- Updated README to reflect the new workflow structure
