 * - Check if all of the dependencies in the monorepo children "package.json" files are non-exact.
 * - Check if any dependencies in the monorepo root "package.json" are unused.
 *
 * This is intended to be called in a monorepo lint script. It will exit the program with an error
 * code of 1 if discrepancies are found.

 *
 * Note that this function is not needed if the monorepo is using the pnpm or bun "catalog" feature,
 * since that will automatically keep package dependencies in-sync.

 * versions. For those cases, the `updatePackageJSONDependencies` function should be used, since it
