[From Arch] Removing python2 from the repositories

Python 2 went end of life January 2020. Since then Arch has been actively cutting down the number of projects depending on python2 in their repositories, and they have finally been able to drop it from our distribution, making it disappear from Parabola too. If you still have python2 installed on your system consider removing it and any python2 package.

If you still require the python2 package you can keep it around, but please be aware that there will be no security updates.
