fix: omit docs version folders from autolink titles

[Ibochkarev]

🔗 Linked issue

Fixes #2163

📚 Description

LinkExample titles turned path segments like 4.x into 4 X, so live-example callouts read Docs > 4 X > Examples….

I skipped N.x folders in createBreadcrumb, pointed ReadMore at the same helper, and added a unit test for the state-management example path.

📝 Walkthrough

Walkthrough

The shared createBreadcrumb utility now removes documentation version folders such as 4.x and 3.x before formatting titles. ReadMore.vue removes its local breadcrumb helper and unused imports, but computedTitle still references createBreadcrumb. Tests cover version-folder omission while preserving surrounding breadcrumb sections.
