Update Drupal core from ~11.3.0 to ~11.4.0 in the Varbase Core module (10.1.x)

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 Core module on the 10.1.x branch (used by Varbase 10.1.x) currently pins Drupal core to ~11.3.0 (see Composer version constraints), so it cannot be installed or updated on Drupal 11.4.x. Related: Drupal core release schedule.

Follow-up: after bumping composer.json and the main varbase_core.info.yml to ~11.4.0, the 8 submodules under modules/*/ were found to still pin core_version_requirement: ~11.3.0, which throws MissingDependencyException: module 'varbase_admin' is incompatible with this version of Drupal core (and equivalent fatals for the other 7 submodules) during drush site:install on Drupal 11.4.x.

Steps to reproduce

On a Drupal 11.4.0 site, install/update Varbase Core from the 10.1.x branch: it is blocked because varbase_core.info.yml and composer.json require ~11.3.0. Even after that is fixed, drush site:install still fatals with MissingDependencyException because the 8 submodules (varbase_admin, varbase_default_content, varbase_development, varbase_internationalization, varbase_page, varbase_security, varbase_tour, varbase_webform) still require ~11.3.0.

Proposed resolution

Update the Drupal core constraint from ~11.3.0 to ~11.4.0 on the 10.1.x branch in composer.json (drupal/core) and varbase_core.info.yml (core_version_requirement).

Also bump core_version_requirement from ~11.3.0 to ~11.4.0 in the 8 submodule .info.yml files under modules/*/ listed above, to match the parent module.
