Easily support :nodoc: suggestions in Github Code Review

[niksawtschuk]

I noticed today that Github released a beta feature for quickly suggesting changes in a PR.

Basically all you have to do is comment a specific change on a line like so (without backslashes):

\```suggestion
someCodeChange()
\```

and it will place a button to quickly apply that suggested change in the Conversation view for a PR. Example:

I think it would be a nice addition to have an automatic suggestion which simply adds :nodoc: to the end of the method or variable definition. I realize that the feature is still in beta though.

That's a really nice suggestion! I'll definitely check it out but theoretically danger should support it...
