fix: #3607041 Bootstrap JavaScript jQuery 4 compatibility on Drupal ~11.3 (core ships jQuery 4)

Closes #3607041.

Drupal 11 core ships jQuery 4. The bundled Bootstrap 4.6 JS gate rejected jQuery >=4 and threw, breaking the front end (sticky header, scroll classes, dropdowns, collapse, modal, carousel). Raise the gate t[0]>=4 -> t[0]>=5 so Bootstrap 4.6 runs on core jQuery 4 (as bootstrap4 3.0.7 / bootstrap 8.x-3.35 did), and add js/bootstrap/README.md documenting the fix and jQuery 3 -> 4 migration for custom themes and modules.

AI-Generated: Yes (Used Claude Code to research and apply the fix).
