Describe the bug
Under certain circumstances, the dependency-check-gitlab.json file has invalid syntax. Specifically, there is a trailing comma after the last package entry in the dependencies section of dependency_files. The dependency-check.json file does not have this issue. This is the section with the trailing comma:

{
"dependencies": [
{"package": {"name": "ComponentSpace.SAML2"},"version": "2.6.0.17"},
{"package": {"name": "select2"},"version": "3.4.3"},
{"package": {"name": "select2"},"version": "3.4.0"},
]
}

Version of dependency-check used
The problem occurs using version 9.1.0 of the docker image - owasp/dependency-check:9.1.0
