How to use the @instructure/pkg-utils.getPackages function in @instructure/pkg-utils

return function (cz, commit) {
    const scope = '@instructure'
    const allPackages = getPackages()
    const changedPackages = getChangedPackages('--cached', allPackages).map(pkg => pkg.name.replace(`${scope}/`, ''))
    const packageNames = allPackages.map(pkg => pkg.name.replace(`${scope}/`, ''))
    const questions = makeDefaultQuestions(packageNames, changedPackages)

    // eslint-disable-next-line no-console
    console.info('\n\nLine 1 will be cropped at 100 characters. All other lines will be wrapped after 100 characters.\n')

          footer,
