[alpha_factory] Fix lint hooks and Insight preview asset checks

[MontrealAI]

Motivation

• Fix failing repository hooks and gallery validation so CI linting and demo preview checks pass.
• Ensure the Insight browser lint step can run by installing the required Node.js version and dependencies.

Description

• Normalize formatting in alpha_factory_v1/demos/alpha_agi_insight_v1/insight_browser_v1/manual_build.py to satisfy the formatter hooks.
• Update tests/test_ci_ruff_scope_contract.py to use consistent quoting and formatting expected by black.
• Add the missing mirrored preview asset at docs/alpha_agi_insight_v1/assets/preview.svg to satisfy gallery validation.
• Accept the workflow action pin update in .github/workflows/ci.yml for the sticky PR comment action.

Testing

• Ran pre-commit run --all-files after fixes and all hooks passed (including black, ruff, flake8, semgrep, and eslint for the Insight browser).
• Installed Node.js 22.17.1 with nvm install 22.17.1 and ran npm ci in alpha_factory_v1/demos/alpha_agi_insight_v1/insight_browser_v1 so the ESLint hook could run successfully.
• Executed pytest tests/test_ping_agent.py tests/test_af_requests.py --cov --cov-report=xml which produced 2 passed, 1 skipped and wrote coverage.xml successfully.
