chore: remove excess Helm packages (6.9.2, 6.9.3, 6.9.4) and update index.yaml

- Delete packages created by previous incorrect version increment logic
- packages/wordpress-nginx-6.9.2.tgz (incorrect - appVersion was 6.9.0)
- packages/wordpress-nginx-6.9.3.tgz (incorrect - appVersion was 6.9.0)
- packages/wordpress-nginx-6.9.4.tgz (incorrect - appVersion was 6.9.0)
- Regenerate index.yaml to include only valid 6.9.1 package
