fix(ci): resolve yamllint errors and regenerate helm-docs

Fixed yamllint configuration and values.yaml issues:
- Added ignore patterns for templates/ and .github/ directories to yamllint config
  (Helm templates contain Go template syntax that conflicts with YAML syntax)
- Removed trailing spaces from values.yaml:123 (nodePort comment)
- Regenerated README.md with helm-docs to sync with values.yaml changes

yamllint now passes without errors (only warnings remain for long lines in docs).
