Documentation: What is the disputes procedure for packages?

The general registry of Julia is a centralized registry similar to NPM. NPM has a disputes procedure for the cases where there is an unmaintained package, and new maintainers want to continue developing it.

> TL;DR
> Get the author email with npm owner ls
> Email the author, CC support@npmjs.com
> After a few weeks, if there's no resolution, we'll sort it out.

In other words: NPM allows the new maintainers to email the old owners of the package and ask them to give them write access. If the authors agree, or they do not respond, NPM itself moves the package to the new owners.

Given the fact that General.jl is similar to npm, there should be a similar mechanism for handling such cases.
