    Exclude po files from pre-commit checks
    
    Since we use these checks in CI but don't use MRs for i18n updates, we
    can't stop bad `.po` file changes getting in to our main release
    branches. In general these changes are likely to be e.g., missing-
    newline-at-EOF style errors, which aren't a good reason to break CI.
