[arch-announce] Planet Arch Linux migration

[Arch Linux: Recent news updates: Jelle van der Waa]

The software behind planet.archlinux.org was implemented in Python 2 and is no longer maintained upstream. This functionality has now been implemented in archlinux.org's archweb backend which is actively maintained but offers a slightly different experience.

The most notable changes are the offered feeds and the feed location. Archweb only offers an Atom feed which is located at [here](https://archlinux.org/feeds/planet).
