fix: when scope is provided use proper separator

it's not documented particularly well but ":" needs to be set between
the scope and "registry" in order to set the proper .npmrc config

https://docs.npmjs.com/files/npmrc#comments

this demonstrates it well although the link is for a different topic

this was incorrectly fixed in verdaccio#34
