Update GitHub Actions questions documentation links and fix syntax errors

GitHub reorganized their Actions documentation structure, deprecating /actions/reference/ and /actions/learn-github-actions/ paths. This PR updates all affected questions to use current documentation URLs.

• Expressions: /actions/learn-github-actions/expressions → /actions/writing-workflows/.../evaluate-expressions-in-workflows-and-actions
• Secrets: /actions/reference/security/secrets → /actions/security-guides/using-secrets-in-github-actions
