.github/stale bot: stop commenting

[ryantm]

Niklas Hambüchen (@nh2) noted in

NixOS/rfcs#124 (comment)

that we can add a label description for the stale label that appears
when you hover over the label, or look on

https://github.com/NixOS/nixpkgs/labels

I set the description to be

https://github.com/NixOS/nixpkgs/blob/master/.github/STALE-BOT.md

which is our page explaining the stale bot.

The stale bot comments/emails are a significant burden on our most
prodigious contributors, and the reason for their existence to orient
new contributors.

Since our stale bot's configuration is benign enough to ignore (it
does not close), I believe it is good enough to satisfy the new
contributor orientation with the label description.

Therefore, this commit disables commenting when labeling an issue or
PR stale.

One other thing to note is that some people like being reminded about their issues that hadn't been active in half a year. But I suspect this benefit only applies to a very small minority of the comments/emails.

There ought to be a way interested parties could query the issues with the API to get this information form the labels too, without having to spam everyone with comments.

Side note: I'm still dreaming about workflow-engine type repo-automation beyond the capabilities of current readily available tooling.

I'm thinking in terms of how a modern and big insurance company would automate their business processes all across the board.

We are a modern and very big open source project.

End sidenote. 😊

I'm still hoping @Profpatsch can comment on this because I feel like he might want to represent the people who liked being notified.

(fixed the bug in label-approved) so the above won't happen again)

last call for @Profpatsch otherwise I would suggest to merge this in the next two or three days.
