IGitHubClient.Release -> IRepositoriesClient.Release

[shiftkey]

This is currently defined as a top-level property, but is documented under /repos/releases in the API:

https://developer.github.com/v3/repos/releases/

var releases = await github.Releases.GetAll("octokit", "octokit.net");

We should mark the top-level property as obsolete and move this under IRepositoriesClient:

var releases = await github.Repository.Releases.GetAll("octokit", "octokit.net");

I'd like to work on this one

Just going through open issues and noticed this one was fixed in #1058 and should be closed

Whoops! The auto-closing of PRs didn't catch this one. Done!
