[BUG] Dead link in warning when importing Danger JS

[bertrand-toca]

Describe the bug
When I use an import statement like this:

import { danger } from 'danger';

I get the warning message described here https://github.com/danger/danger-js/blob/491bb0b401148366cbe0e4d2bc9705fea521a647/source/danger.ts#L13C5-L13C66

Hey there, it looks like you're trying to import the danger module. Turns out
that the code you write in a Dangerfile.js is actually a bit of a sneaky hack. 

When running Danger, the import or require for Danger is removed before the code
is evaluated. Instead all of the imports are added to the global runtime, so if
you are importing Danger to use one of it's functions - you should instead just
use the global object for the root DSL elements.

There is a spectrum thread for discussion here:
  - https://spectrum.chat/?t=0a005b56-31ec-4919-9a28-ced623949d4d

That spectrum link doesn't exist anymore.

To Reproduce
Steps to reproduce the behavior:

1. Add this line in a danger.ts: import { danger } from 'danger';
2. Run Danger

Expected behavior

Get a warning with a non-dead link, or amend the warning message so the link isn't needed.

#1153 (reply in thread) would make a good replacement

PR with that link: #1480

I thought about trying to reword it all to embed it in the plain text of the thrown exception, but I think the link to the GitHub discussion is more effective/practical for now.
