Remove duplicated line from Maven CI template
Context
GitLab CI pipeline templates: Maven
Problem
By selecting the Maven template, the first line is duplicated such as:
# This file is a template, and might need editing before it works on your project.
# This file is a template, and might need editing before it works on your project.
# Build JAVA applications using Apache Maven (http://maven.apache.org)
# For docker image tags see https://hub.docker.com/_/maven/
.
.
.
Reason: the first line ("This file is a template, and might...") is already automatically inserted when the template is applied. So it doesn't need to be part of the actual template pipeline configuration.
