Update Drupal Core from ~11.3.0 to ~11.4.0 in the Varbase Project template

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 Project composer template currently pins Drupal core packages to ~11.3 / ~11.3.0 (see Composer version constraints), so a new install cannot use Drupal 11.4.x. Related: Drupal core release schedule.

Steps to reproduce

Run composer create-project drupal/varbase_project:~11: the Drupal core packages resolve to 11.3.x because the template pins ~11.3.

Proposed resolution

Update the Drupal core constraint from ~11.3 to ~11.4 in composer.json: drupal/core-composer-scaffold, drupal/core-project-message, drupal/core-recipe-unpack, drupal/core-recommended, drupal/core-vendor-hardening, and drupal/core (~11.3.0 to ~11.4.0).
