Add Gitlab CI integration

by using PHP CS Fixer for linting instead of PHPCS and dropping PHPStan 2.x as requirement due to the lack of support for that before 11.2.0.

+# GitLabCI template for Drupal projects.
+#
+# This template is designed to give any Contrib maintainer everything they need to test, without requiring modification.
+# It is also designed to keep up to date with Core Development automatically through the use of include files that can be centrally maintained.
+# As long as you include the project, ref and three files below, any future updates added by the Drupal Association will be used in your
+# pipelines automatically. However, you can modify this template if you have additional needs for your project.
+# The full documentation is on https://project.pages.drupalcode.org/gitlab_templates/
+################
+
+# For information on alternative values for 'ref' see https://project.pages.drupalcode.org/gitlab_templates/info/templates-version/
+# To test a Drupal 7 project, change the first include filename from .main.yml to .main-d7.yml
