Update .gitlab-ci.yml file

.gitlab-ci.yml

+# This file is a template, and might need editing before it works on your project.
+# This is a sample GitLab CI/CD configuration file that should run without any modifications.
+# It demonstrates a basic 3 stage CI/CD pipeline. Instead of real tests or scripts,
+# it uses echo commands to simulate the pipeline execution.
+#
+# A pipeline is composed of independent jobs that run scripts, grouped into stages.
+# Stages run in sequential order, but jobs within stages run in parallel.
+#
+# For more information, see: https://docs.gitlab.com/ee/ci/yaml/index.html#stages
+#
+# You can copy and paste this template into a new `.gitlab-ci.yml` file.
+# You should not add this template to an existing `.gitlab-ci.yml` file by using the `include:` keyword.
+#
