Update Drupal Core from ~11.3.0 to ~11.4.0 in the Varbase Starter recipe

Problem/Motivation

Drupal 11.4.0 stable was released on 1 Jul 2026 by catch: https://www.drupal.org/project/drupal/releases/11.4.0

This is a feature minor release of Drupal 11 and is ready for use on production sites. Learn more about Drupal 11 and the Drupal core release cycle. Read the Drupal 11.4.0 release announcement for improvements and highlights in this release.

The Varbase Starter site template currently pins Drupal core to ^11.3 (see Composer version constraints), so it cannot pull in Drupal 11.4.x. Related: Drupal core release schedule.

Steps to reproduce

Install Varbase Starter and try to update Drupal core to 11.4.0: it is blocked because the template pins drupal/core: ^11.3.

Proposed resolution

Update the Drupal core constraint from ^11.3 to ^11.4 in composer.json (drupal/core) and in recommended.yml (core: '^11.3' to '^11.4').
