86230b27 - refactor(cna): use Commander `args` instead of `process.argv` (#68454)

refactor(cna): use Commander `args` instead of `process.argv` (#68454) ### Why? Resolve left-out refactors from #68233 ### How? Used Commander's `args` and `opts` values, which remove a few lines. Synced the variable name for the `app` value for consistency and possible future destructuring.
