chore: replace bitnami readme-generator with helm-docs

[alambare]

• Convert all ## @param/@section annotations in values.yaml to helm-docs inline # -- format
• Add README.md.gotmpl to preserve static sections (TL;DR, Prerequisites, install/uninstall, configuration details, license)
• Add helm-docs-container pre-commit hook (runs via Docker, no local install needed, enforced in CI via tox linters env)
• Add 'make helm-docs' target for manual regeneration
• Remove package.json (no more npm dependency)
