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.

The list of tools included was based on a mixture of
- Download counts
- Word of mouth exposure
- Unique aspects covered
- Maturity

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.
