chore: remove arguments from pack.sh (aws#2374)

Not all `npm run package` scripts accept arguments, and in fact the
handwritten ones that end in ` ... && npm pack` will break, because when
executing `pack.sh -v` (for verbosity in packages that use
cdk-build-tools) they will execute `npm -v` instead of `npm pack
-v`.

This is not safe!
