fix(cli): handle list response for json/yaml output

JohnVillalovos · nejch · commit 9b88132078ed · 2022-10-06T09:24:02.000+02:00
Handle the case with the CLI where a list response is returned from GitLab and json/yaml output is requested. Add a functional CLI test to validate it works. Closes: #2287
