Deleting package.json before npm installing cli and aws-sdk in GH actions

[barankyle]

Summary

npm will always install all of a found package.json's files even if you
want to just install one or two specific packages. This was greatly
slowing down the builder build process in GH actions. Removing the root
package.json resolves the issue, and that step takes mere seconds now.
