fix(Docs) integrations without conditionals were hidden by default

Fix: Integrations wrapper incorrectly hidden when no onboarding options present

Problem

Regression from #15160 - integrations: [...] wrapper was always hidden by default in code blocks, even when the integrations inside should always be visible (e.g., integrations: [Sentry.captureConsoleIntegration()]).

The wrapper was only restored to visible by updateElementsVisibilityForOptions, which never runs on pages without onboarding option buttons.

Root Cause

In src/rehype-onboarding-lines.js, the integrations wrapper was unconditionally hidden at build time, relying on client-side JavaScript to show it when appropriate. Pages without <OnboardingOptionButtons /> never executed the restore logic.

Solution

Updated the build-time logic to only hide the integrations wrapper when ALL content inside is conditional (wrapped in ___PRODUCT_OPTION_START/END___ markers). If any integration is always-visible (no onboarding option), the wrapper remains visible by default.

Scenarios Now Handled Correctly

• ✅ Always-visible integrations only → wrapper always shown
• ✅ All conditional integrations → wrapper hidden/shown based on option selection
• ✅ Mixed (some always-visible + some conditional) → wrapper always shown, conditional lines toggle independently
• ✅ Empty inline arrays integrations: [] → unaffected (not matched by regex)
