update "screenshot" of running gitlab-runner without arguments. from version 1.0.0 to 13.0
What does this MR do?
The documentation contains the output of running the gitlab-runner command without arguments. The old "screenshot" uses version 1.0.0-beta of gitlab-runner. Commands that have been added in later versions such as "list" are not visible in the screenshot, but are later mentioned in the documentation. This MR uses the output of gitlab-runner version 13.0.0 instead of the outdated version.
