Build the CI composer job against Drupal 11.4.0 on the 3.1.x branch

Problem/Motivation

The 3.1.x branch targets Drupal ~11.4.0, but its GitLab CI composer job overrides before_script without a job-level DRUPAL_CORE variable, so the DrupalCI template default wins and the job (and the webship-js-test browser job that depends on it) actually build and run on Drupal 11.3.12, not 11.4. The pipeline reports green while never validating the real ~11.4 target.

Steps to reproduce

Proposed resolution

Add job-level variables: DRUPAL_CORE: "11.4.0" and IGNORE_PROJECT_DRUPAL_CORE_VERSION: "1" to the composer job in .gitlab-ci.yml so the whole pipeline resolves and tests against Drupal ~11.4.0.
