    ci: Ensure we clone a deep enough history for commit review
    
    It seems gitlab changed something recently in the default clone depth
    which made MRs with >10 commits to obscurely fail in the review stage.
    As per https://docs.gitlab.com/ee/ci/yaml/#shallow-cloning, bump it
    to 100 to allow bigger MRs.
