* gitlab_project_variable - use find_project() for consistent error handling
Replace the bare projects.get() call in GitlabProjectVariables.get_project()
with find_project() from module_utils/gitlab, which all other GitLab modules
already use. This ensures a graceful fail_json (with a clear error message)
when the project is not found, rather than an unhandled GitlabGetError
propagating as a module traceback.
