package unpublished and 404 cleanup

[wraithgar]

Two commits here, one removes the user name from the unpublished message, as that's no longer returned by the npm registry. The second one removes the "bug the author" message from the package 404, that copy is outdated and from a different era.

Going to also add a commit removing the "bug the author" message on a 404.

That seems like a registry change that would break older and current clients; can the registry send that value even if modern npm isn’t using it?

[ljharb]

Seeing a related PR, how is it a privacy concern to tell me my own name?

[wraithgar]

The registry doesn't send that anymore, so this cleans the message up. Having the npm registry send dummy data there for old clients would be something you can request via https://www.npmjs.com/support

[ljharb]

Right, but why did the registry stop sending that info? and when was that breaking change announced?
