When setting up a Microsoft Teams integration, admins need to create an

incoming WebHook via the Microsoft Teams app. When creating the WebHook, you

have the ability to upload a picture to associate with all messages coming

from the WebHook (basically an avatar).
Since we don't have control over this, we offer a link to a Review Board logo

in our docs that admins can upload. This logo differs from our normal logo by

being centered, so that it looks nice in the rounded crop that most chat

applications use for avatars. We recently added this centered logo to our

CDN, so this updates the docs to use the right URL for the centered logo.

Accessed the URL and made sure it lead to the centered logo.
