Feature summary: Add a link to the diff on https://wikitech.wikimedia.org/wiki/Deployments when a patch has been added
Use case(s): When you successfully add a patch to https://wikitech.wikimedia.org/wiki/Deployments via the Schedule Deployment tool, the message letting you know that it was successful should include a link to the diff on that Wikitech page, so that you can easily verify that it was added correctly.
Benefits: Gives an easy link to verify that the change was added, and also lets you see how many/which other patches are already in the same deployment window.
