fix(og-image): bump to 6.3.6, remove workarounds

6.3.6 fixes:
- Hash propagation: buildOgImageUrl result.hash is now written to
  opts._hash so the prerender plugin stores it in prerenderOptionsCache
- Orphaned hash URLs are gracefully skipped (prerender:generate hook
  clears error) instead of failing the build
- Signed dynamic URLs when strict+secret are set (from 6.3.5)

Removed workarounds that are no longer needed:
- nitro.prerender.ignore for /_og/ paths
- @nuxtjs/html-validator patch for /_og/ route skip
