docs(ref): Establish publish best practices

Inspired by rust-lang#841 and conversations at RustConf.

At RustConf, someone was talking to me about the lack or inconsistent
use of best practices within the crate ecosystem.
We have a challenge of needing to help users get up and going who can't
research every last decision while not over-encouraging the status quo,
leading to stagnation.

I do have a bias in this conversation as the maintainer of one of these
tools which is why I decided to pick an ordering without judgement.
I picked alphabetical ordering before sorting and realizing this puts my
own crate first.
