Remove outdated quicli comments from init.rs

[data-pup]

Now that quicli is not in the dependencies, the comments above init::create_pkg_dir are outdated. Further, I believe the full paths to result::Result are no longer needed in the various function/method definitions, since that conflict is no longer caused by quicli::prelude.

Assuming I'm right about all of that, I was thinking this could be a pretty straightforward thing to fix, and a good task for someone new to OSS contribution. I can take care of this tomorrow if that sounds good to you, I'll was planning to use it as a pairing exercise with someone 😄
